MISP is an open source threat intelligence platform where analysts log indicators and incidents, see how they connect, and share them with trusted organizations. Each case is an event holding attributes and structured objects such as files, network connections, and email messages, with Markdown reports beside the machine-readable data. A correlation engine links events that share values, including fuzzy-hash and CIDR matches, and warning lists flag benign values before they cause false positives. Taxonomies and galaxies tag events with TLP levels, threat actors, malware families, and MITRE ATT&CK techniques. Analysts explore relationships in an event graph and a correlation graph with a timeline, and build drag-and-drop dashboards with maps and ATT&CK heatmaps. Sharing groups control who sees which event, and instances synchronize with partner organizations with distribution settings down to a single attribute. Free-text, URL, bulk, and STIX imports fill the database, and exports reach Suricata, Snort, Zeek, OpenIOC, CSV, STIX 1 and 2, and RPZ zones. A REST API, the PyMISP library, expansion modules, and workflows enrich data and automate publishing. ZeroMQ and Kafka streams announce every change to connected tools.

Turn ordinary IP cameras, USB webcams, and video files into a self-hosted surveillance system that watches, records, and replays everything from a browser. Every camera becomes a monitor that can capture, analyze, and record around the clock or only when motion appears. Draw detection zones in six types (active, inclusive, exclusive, preclusive, inactive, and privacy) so a visitor on the driveway raises an alarm and swaying trees do not. The Montage view tiles live feeds in selectable layouts, Cycle rotates through them, and the Watch view adds scale, stream quality, and player controls for a single camera. Events arrive in a sortable list with thumbnails, durations, and alarm scores, play back against a timeline, and can be reviewed across every camera in Montage Review. Filters automate housekeeping by archiving, emailing, messaging, uploading, copying, moving, or deleting matching events on a schedule. PTZ controls steer supported cameras. User roles limit who can view or change each monitor, a REST API and MQTT support connect other tools, and the optional event server adds push notifications and object detection through machine-learning hooks. Multi-server installs spread cameras and storage across machines, and the zmNinjaNg app brings the same views to phones and desktops.

Backed by over 8,700 GitHub stars and OpenID Connect certification, Pocket ID delivers what enterprise identity platforms like Keycloak provide but without the configuration complexity — a passkey-only OIDC provider purpose-built for homelabs and small deployments. The core design decision is radical simplicity: no passwords exist in the system, only WebAuthn-based passkeys using hardware security keys, TouchID, FaceID, or device PINs, making phishing attacks structurally impossible rather than merely discouraged. The Go backend built on the Gin framework serves a compiled SvelteKit frontend as static assets, running as a single Docker container with SQLite as the default database and optional PostgreSQL for larger deployments. User management supports manual creation, signup links, and open registration, with group-based access control that restricts which OIDC clients each group can access and attaches custom claims for downstream role mapping. LDAP synchronization pulls users and groups from OpenLDAP or Active Directory, while SCIM support enables automated provisioning from compatible identity sources. Federated client credentials handle machine-to-machine authentication for service-to-service communication patterns. The audit system logs every authentication event with GeoIP enrichment, sends email notifications for sign-ins from unknown devices, and provides one-time login codes for accessing accounts from devices without passkey support. TLS with HTTP/2 is built in, PKCE adds code exchange protection, and OpenTelemetry provides tracing and metrics integration.

Watchtower puts AI-driven security assessments into one web console, where sessions probe your attack surface while every request, finding, and piece of evidence is captured as it happens. The AI session console follows the attack surface, session progress, tool calls, and findings as an assessment runs, so you can watch an engagement unfold instead of reading a log afterwards. A built-in proxy workflow records HTTP and HTTPS traffic history with highlighted patterns, and any captured request can be sent to the Repeater for editing, replay, and response comparison. Mobile work is covered too: connect phones over USB or wireless, capture app traffic separately from accessibility control, and import WeChat mini-program packages to configure an assessment session. A public vulnerability intelligence library can be searched by component, severity, and source and kept synchronized locally, giving assessments current context without sending your targets anywhere. Findings are managed by source, severity, and status, each linked back to its supporting evidence, and the report editor assembles them with a live preview, impact notes, and remediation guidance. The dashboard tracks assets, tasks, AI sessions, token usage, and runtime resources, and task admission is budgeted against physical memory so heavy scans do not starve the host. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. GPL-3.0 licensed.

Big repositories, small questions: Open Kritt is a self-hosted platform that splits vulnerability research into focused tasks for AI agents and returns ranked, de-duplicated findings. Build a workflow as a tree of prompt steps, where each step declares the structured output it must produce and the next level launches one fresh agent per result. Scan remote or local repositories along with their dependencies, using Codex, Claude Code, or Grok Build as the harness. Every workflow ends in one fixed finding schema covering file, line, vulnerability type, trigger flow, and a malicious input example. Post-scripts then validate each finding, build a proof of concept, or write the report. Markdown severity rankers tell the model how to prioritize for your bounty program, and repeated findings collapse automatically. Model access comes from a Codex login or OpenAI, Anthropic, DeepSeek, OpenRouter, or xAI keys, with an Active switch to choose which accounts take new work. A dashboard tracks blueprints, scans, and findings, a headless command-line tool imports workflows and launches scans on servers without a browser, and finished scans export as one ZIP with a share-safe manifest. Built-in workflows, including an entry-point-driven hunt, give you a starting point.

Authelia is the leading open-source SSO and multi-factor authentication server for self-hosted infrastructure. The Go backend compiles to a single binary or Docker container image, serving a TypeScript React web portal that handles first-factor username and password login, second-factor authentication via TOTP, WebAuthn FIDO2 security keys, passwordless passkeys, and Duo mobile push notifications, and an OpenID Connect 1.0 and OAuth 2.0 identity provider with device code flow, JWE encrypted ID tokens, custom claims policies, and network-scoped authorization criteria. The forward authentication model integrates with Nginx auth_request, Traefik ForwardAuth, HAProxy, Caddy, Envoy, SWAG, and Skipper reverse proxies, injecting Remote-User, Remote-Groups, and Remote-Email headers into authorized requests. Granular access control rules match subject, groups, request URI, HTTP method, and network to enforce one-factor and two-factor policies per route. The user backend supports LDAP with attribute mapping, connection pooling, and bind mode, or YAML file-based authentication with Argon2id hashed passwords. Session state stores in Redis for high availability across clustered deployments, while persistent data lives in SQLite, MySQL and MariaDB, or PostgreSQL. Brute force protection locks accounts after configurable failed attempts, and email-based identity verification handles password resets and device registration. Dark, light, and OLED themes with i18n localization customize the portal appearance. On RepoCloud, deploy Authelia on a dedicated VPS with Docker, root SSH access, and complete control over your authentication infrastructure, all under the Apache-2.0 license.

Social Analyzer scans over 1,000 social media platforms in parallel to discover and correlate user profiles from a single username query, making it the most comprehensive OSINT reconnaissance tool of its kind. Three detection modes cover different accuracy and speed tradeoffs: fast HTTP library checks for rapid sweeps, Selenium WebDriver validation for JavaScript-heavy sites, and a special mode for stubborn edge cases. String analysis generates username permutations and combinations to catch related accounts with slight naming variations. Three interfaces serve different workflows: a Node.js web application on port 9005 with a browser-based GUI, a CLI for scripted batch operations, and Python plus Node.js APIs for embedding into automated investigation pipelines. The QeeqBox OSINT library extracts profile metadata, screenshots, titles, descriptions, and activity patterns, all visualized through Ixora-based force-directed graphs that map relationships between discovered accounts. Tesseract OCR analyzes profile images for additional detection vectors. Search results narrow by country codes, website categories, Alexa ranking thresholds, and confidence levels. Optional Google API and DuckDuckGo API integration adds search engine correlation alongside direct platform queries. Docker deployment bundles Node.js, Firefox ESR, Tesseract, and all dependencies into one container. Trusted by law enforcement and security researchers for digital forensics and identity verification. 23,000+ GitHub stars. AGPL-3.0 licensed.

With over 34,000 GitHub stars and backing from a well-funded engineering team, Tailscale has fundamentally simplified how developers and system administrators think about secure networking. The client daemon establishes WireGuard tunnels directly between devices using sophisticated NAT traversal techniques, achieving direct peer-to-peer connections in the vast majority of network configurations without requiring port forwarding, firewall rules, or VPN concentrators. When direct connections prove impossible due to restrictive network environments, DERP relay servers provide encrypted fallback paths. MagicDNS assigns human-readable hostnames to every device on the network, eliminating the need to remember IP addresses across a tailnet. Subnet routing allows nodes to advertise access to entire local networks, enabling remote access to office resources, home labs, or cloud VPCs through a single gateway node. Exit node functionality routes all internet traffic through a designated device for privacy protection or geographic flexibility. Access control lists define granular policies for which devices and users can communicate with which services, enforced cryptographically at the network layer. The authentication layer integrates with identity providers including Google, Microsoft, GitHub, Apple, and OIDC-compliant systems for single sign-on access. Taildrop enables direct encrypted file transfers between devices without cloud intermediaries. The tailscale CLI provides complete network management from the terminal including status monitoring, route advertisement, and node configuration. Running Tailscale on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console provides a permanent, always-on node in your mesh network.

Fleet lets IT and security teams query every device in their organization like a SQL database, using osquery to surface installed software, running processes, configurations, and vulnerabilities within seconds across macOS, Windows, Linux, iOS, Android, and ChromeOS. The Go-based server exposes a web console and REST API for centralized device management, with MDM capabilities built on nanoMDM for Apple device enrollment, configuration profiles, and remote lock or wipe. Vulnerability management cross-references installed software inventories against NVD and OVAL CVE databases, automatically flagging known vulnerabilities with severity scores and remediation guidance. Software deployment handles OS updates using Apple Declarative Device Management, Windows Update, and custom installer packages distributed through S3-compatible storage. A GitOps workflow enables infrastructure-as-code management where device policies, osquery queries, and configuration profiles live as YAML files in Git repositories, with CI/CD pipelines pushing changes through the fleetctl CLI. The fleetd agent bundle includes osquery for telemetry, Orbit for version management, and Fleet Desktop providing end users a menu bar status indicator. Integrations connect to Snowflake, Splunk, Elastic, Jira, Zendesk, Vanta, and GitHub Actions for automated compliance reporting. CIS benchmark policies verify security baselines across operating systems. Deployment requires MySQL for persistence and Redis for caching, running as Docker containers or on Kubernetes.

OpenSearch is a search and analytics platforms, powering full-text search, log analytics, observability, and AI-powered vector retrieval at petabyte scale. The distributed engine provides BM25 full-text search alongside k-NN vector search using NMSLIB, Faiss, and Lucene libraries, enabling semantic search, hybrid search combining keyword and vector scoring through normalization processors, neural sparse search, and retrieval-augmented generation workflows with built-in ML Commons for model hosting. OpenSearch Dashboards delivers interactive visualization with Discover for log exploration, custom dashboards, alerting, anomaly detection using Random Cut Forest algorithms, and Security Analytics with detection rules mapped to MITRE ATT&CK. Native Prometheus integration with full PromQL support unifies metrics alongside logs and traces in a single observability interface, while Data Prepper handles telemetry ingestion from OpenTelemetry collectors, Fluent Bit, and Logstash-compatible pipelines. SQL and Piped Processing Language queries with a visual PPL builder enable analysts to query data without learning the native DSL. Index State Management automates index lifecycle with rollover, shrink, and delete policies, while cross-cluster replication and searchable snapshots on S3-compatible storage provide disaster recovery. Scoped API keys, field-level security, document-level security, and audit logging deliver enterprise-grade access control. Docker Compose deploys multi-node clusters alongside the Kubernetes operator for orchestrated production environments.

PrivateBin shares text and files with true zero-knowledge encryption: the server stores only ciphertext it cannot decrypt because the key exists exclusively in the URL fragment that never reaches the server. With over 8,400 GitHub stars and 500,000+ Docker pulls, it has become the standard for privacy-respecting paste sharing where not even the hosting operator can read stored content. All encryption uses 256-bit AES in Galois Counter mode performed entirely client-side in the browser. Burn-after-reading mode destroys pastes on first view, while configurable expiration timers automatically purge content after periods ranging from five minutes to forever. Optional password protection adds a second encryption layer requiring recipients to enter a passphrase before decryption occurs. Discussion threads enable anonymous or nickname-based commenting on pastes with IP-based identicon avatars for visual identity. Markdown rendering with live preview formats pastes as styled HTML, and syntax highlighting through prettify.js supports dozens of programming languages across four color themes. File upload support enables sharing images, PDFs, and media files with in-browser preview. QR code generation converts paste URLs for mobile device transfer. Customizable templates include Bootstrap 5, classic Bootstrap CSS, and Darkstrap themes. Storage backends support filesystem, MySQL, PostgreSQL, SQLite, Amazon S3, and Google Cloud Storage. Deploy via Docker with the privatebin/nginx-fpm-alpine image on port 8080.

The CAPTCHA bargain - annoy your users and feed their behavior to Google - gets replaced with economics by mCaptcha. Instead of image puzzles, it uses SHA256 proof-of-work: every visitor's browser silently solves a small computational challenge (via a WebAssembly library) before submitting a form. Humans never notice the milliseconds; bots hammering your site must burn more compute sending requests than your server spends answering them, which makes attacks more expensive than defense - the property that also makes mCaptcha genuine DoS protection, not just bot filtering. Written in Rust, the system is fully automated: difficulty scales with traffic, so challenges stay trivial in normal conditions and harden under attack. The privacy and accessibility wins are structural rather than promised: no tracking, no profiling, no user-pattern data collection, and no visual puzzles that exclude users with visual or cognitive impairments - the design was published in Communications of the ACM. Rate limiting is IP-independent, so users behind NATs, VPNs, or Tor get the same experience instead of endless challenge loops, and proofs resist replay attacks, neutering captcha farms. Migration is deliberately easy: the API is compatible with reCAPTCHA and hCaptcha, making it a drop-in replacement. AGPL-licensed core with proprietary-friendly client libraries.

'Can Maria edit this document?' is a simple question with a hard implementation, and SpiceDB is the open-source, Zanzibar-inspired database built to answer it and millions like it correctly. You model your product once in its schema language, defining object types like documents and organizations, relations like owner and member, and computed permissions built from unions, intersections, exclusions, and arrows through other objects. Your application then writes relationships as users join groups, create folders, and share files, and SpiceDB evaluates checks against that live graph in milliseconds. Check a single permission before rendering a button, check hundreds at once to filter a dashboard, look up every resource a user can open for search prefiltering, or list every subject who can access a file for an admin screen. Per-request consistency options, anchored by revision tokens, protect you from the classic race where a revoked user briefly keeps access, and caveats add conditional rules based on context like IP address or time. Relationships persist in PostgreSQL for simple deployments or CockroachDB and Spanner when you need multi-region scale, and the same schema files validate in CI with the command-line tool before they ever reach production. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. Apache-2.0 licensed.

Ory Hydra is an OpenID Certified OAuth 2.0 and OpenID Connect provider that plugs into any existing user database or authentication system through a headless consent and login bridge, letting you own your authorization infrastructure without rebuilding identity management from scratch. The Go binary ships at under 15MB with zero system dependencies and exposes two distinct API surfaces: a public endpoint on port 4444 handling authorization code flows, token exchanges, PKCE challenges, device authorization grants per RFC 8628, and OpenID Connect discovery, plus an admin endpoint on port 4445 managing client registration, token introspection, consent session lifecycle, and JWKS rotation. Access tokens can be issued as opaque reference tokens or signed JWTs for stateless validation at resource servers, while refresh token rotation, token revocation per RFC 7009, and pairwise subject identifiers provide granular security controls. Persistent storage spans PostgreSQL, MySQL, and CockroachDB with automatic schema migrations, and the architecture supports horizontal scaling behind load balancers with shared database state. Dynamic client registration per RFC 7591 enables automated provisioning, and the OAuth 2.0 Threat Model security considerations are implemented as default behaviors rather than optional add-ons. Trusted by OpenAI and other internet-scale platforms. Helm charts and Docker Compose quickstarts provide production-ready deployment paths alongside the broader Ory ecosystem including Kratos for identity management, Oathkeeper for zero-trust API proxying, and Keto for fine-grained permissions.

Behind one admin panel, DefGuard runs a WireGuard VPN, an identity provider, and multi-factor authentication, so every person and device proves who they are before reaching your private network. Administrators define VPN locations, assign which users and groups may enter each one, and enforce firewall rules that allow or deny traffic per location, with changes applied to gateways in real time. People enroll remotely through a guided self-service flow, register their own laptops and phones, and connect with desktop and mobile clients that show live connection statistics. Sign-in goes well beyond passwords, because the built-in OpenID Connect provider gives internal tools single sign-on, while TOTP codes, WebAuthn and FIDO2 keys, email tokens, and mobile biometrics gate each connection. Directory teams sync accounts from LDAP and Active Directory, or federate sign-in through Google, Microsoft, and custom OpenID providers, instead of maintaining a separate user list. Every authentication, enrollment, and policy change lands in a searchable activity log, and webhooks plus a REST API let surrounding systems react to access events automatically. Gateways keep enforcing access from a local cache when the control plane is unreachable, and several gateways can front the same location for failover.

Certificate lifetimes are collapsing toward 47 days, which turns TLS from a yearly chore into a weekly one, and CertMate is the control plane that makes that schedule boring. It issues and renews certificates from Let's Encrypt, ZeroSSL, Google Trust Services, Actalis, DigiCert, SSL.com, Sectigo, or your own private CA, validating by DNS-01 through 29 DNS providers, HTTP-01, or a CSR whose private key never leaves the device. Renewals run automatically, earlier when a certificate's life is short or the CA moves the date through ARI, and deploy hooks push each renewed certificate where it is actually served, then probe the live endpoint to prove the new certificate answers. Discovery watches hosts and certificate transparency logs for certificates you did not issue, folding them into one inventory of what is served where and when it expires. Certificates rest on local disk or in Azure Key Vault, AWS Secrets Manager, HashiCorp Vault, Infisical, or S3 storage, with encrypted backups copied off-site. Its built-in CA issues client certificates for mTLS with OCSP and CRL, and can serve ACME itself, so certbot, lego, acme.sh, and cert-manager get internal certificates under EAB rules you define. Every action lands in a tamper-evident, hash-chained audit trail you can export and verify independently.

Enterprise security stacks assume an enterprise budget; Wildbox assumes a server you already own. It runs your whole security operation as a set of cooperating services behind a single HTTPS gateway: threat intelligence collectors pull indicators from seven public feeds on a schedule, starting with abuse.ch's Feodo Tracker, and every indicator is searchable in one place. Fifty-two security tools sit behind one API, covering DNS, TLS, email security, headers, and port analysis. The cloud posture service runs 22 configuration checks against your live AWS accounts and keeps each scan's report, while the vulnerability service inventories your assets, prioritizes findings by risk, and tracks them through remediation with SLA checks and alert rules. When something needs doing, YAML playbooks execute response workflows as background jobs, and the agents service writes Claude-generated threat-enrichment reports for suspicious indicators when you give it an API key. An osquery-based sensor streams endpoint telemetry from your hosts into the platform, kept separate per team. Users, teams, roles, and scoped API keys live in the identity service, and the backends accept nothing that did not arrive through the gateway, so your security data never leaves hardware you control. Optional Compose profiles add n8n automation and Prometheus monitoring. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console.

Eliminate scattered configuration files and leaked credentials across development teams with Shelve, an open-source secrets management platform that secures environment variables across development, staging, and production tiers. Engineering teams can organize sensitive database passwords and third-party API credentials within a centralized vault protected by AES-256 encryption and SHA-256 integrity verification. The platform synchronizes configurations directly to GitHub Actions and repository secret stores through an official GitHub App integration. Developers can inject encrypted variables directly into local processes using the dedicated CLI without saving plain-text secrets to disk. The built-in sharing vault creates self-destructing, password-protected links to exchange sensitive credentials securely with external contractors. Administrators can define custom workspace teams with granular role-based access controls, track change audit logs across configuration histories, and navigate management views using a keyboard-driven command palette. Automated schema validation engines detect missing parameters and enforce uniform uppercase naming standards across application tiers.
