Every service you self-host wants its own account database, and Kanidm exists so they can all share one: one identity server where people sign in with passkeys and every application trusts the same login. Users register YubiKeys, Touch ID, Windows Hello, or TPM backed authenticators, and attested passkey policies let administrators restrict sign-in to specific authenticator models in high security environments. Applications connect as OAuth2 or OpenID Connect clients with authorization code, client credentials, PKCE, token exchange, and revocation supported, so your wiki, Git forge, and file sync all delegate sign-in instead of storing passwords. The application portal gives each person one page of tiles for every service they may open, and role based access control decides which groups see which applications and scopes. Older systems that only speak LDAP bind to the read-only LDAPS gateway, while Wi-Fi and VPN gear authenticates through the built-in RADIUS server with MS-CHAPv2 and EAP-TLS. Linux machines join through the Unix client for PAM and NSS authentication, cached offline credentials protected by the machine TPM, and SSH keys distributed from the server to every host. A second server replicates the whole database with strong eventual consistency, every node accepting writes without elections or quorums, so a failed machine never locks your users out of sign-in.

Artifact Keeper serves as a self-hosted universal software artifact repository that consolidates container images, application libraries, and infrastructure bundles under a unified management control plane. Software development teams can publish and resolve dependencies using their existing build tools, including Docker, Helm, npm, PyPI, Maven, Cargo, NuGet, and Terraform without installing proprietary client plugins. Remote repositories act as transparent pull-through caching proxies for public upstreams like Docker Hub and PyPI, accelerating internal CI/CD build speeds while insulating production pipelines from external registry outages. Virtual repositories combine multiple local, remote, and third-party endpoints into single URLs, resolving packages across prioritized internal teams and public registries automatically. Automated security scanners evaluate incoming packages for Common Vulnerabilities and Exposures using Trivy and Grype engines, assigning letter grades and enforcing quarantine policies to block vulnerable binaries before production release. Administrators can sign package metadata with cryptographic GPG keys, configure peer mesh replication across geographic regions, and manage team permissions using OpenID Connect, SAML, and granular access tokens.

Trusted by over 60,000 organizations worldwide with more than 8,100 GitHub stars since 2010, Graylog has established itself as one of the fastest paths from raw log data to operational visibility, delivering centralized log management, security analytics, and compliance auditing through a purpose-built web interface with sub-second search at scale. The platform ingests logs from virtually any source via syslog, GELF, Beats, raw TCP/UDP, HTTP, CEF, IPFIX, and Netflow protocols, processing each message through configurable pipelines that parse fields, apply transformations, enrich events with GeoIP data from MaxMind or IPinfo lookup tables, and route messages to appropriate streams based on content rules. OpenSearch handles full-text indexing and storage with dynamic shard sizing that automatically calculates appropriate sizes from available node memory, while MongoDB stores configuration metadata including user accounts, roles, dashboards, alert rules, and pipeline definitions. The alerting system integrates with Slack, PagerDuty, and email with customizable notification templates and Replay Search links for immediate investigation context. Version 7.0 introduced MCP server integration for connecting preferred LLMs to perform AI-assisted log analysis and automation, while version 7.1 added Sigma detection rule import from private GitHub, GitLab, and Bitbucket repositories for detection-as-code workflows. The Sidecar agent management system centrally configures and deploys Filebeat, Winlogbeat, and nxlog collectors across infrastructure from the Graylog web interface.

Four hundred servers need a security patch, they run five different Linux distributions, and a spreadsheet says which ones were done. Uyuni replaces that spreadsheet: one server inventories your fleet, mirrors the software channels each machine subscribes to, and shows exactly which patches and errata apply where. Administrators register clients manually, by bootstrap script, or automatically through activation keys, then group them into systems sets so an action aimed at a group lands on staging first and production on schedule. Patch management creates and applies errata with CVE context, and CVE audits check systems against vulnerability data so you can prove a fix landed instead of believing it did. Configuration channels push files, directories, and symbolic links rendered with Jinja templates through the built-in Salt master, which also runs remote commands and orchestration across tens of thousands of clients. The Content Lifecycle Manager promotes package sets from development through testing to production channels, so every environment consumes tested content in order. Provisioning reinstalls or network-boots machines through PXE with AutoYaST, Kickstart, or cloud-init profiles, proxies cache content for branch offices, and built-in Prometheus and Grafana monitoring watches the management server itself.

Give every laptop, server, and cloud VM you own one private address that works from anywhere, and that is exactly the overlay network Nebula builds. Each machine runs a single small binary, presents a certificate signed by your own certificate authority, and joins a peer-to-peer layer-3 mesh where tunnels form on demand between hosts that need to talk. Lighthouse nodes, the piece you park on a VPS, keep track of where every peer can be reached and introduce hosts to each other, so machines find each other without any central VPN concentrator carrying their traffic. UDP hole punching and keepalive packets open direct tunnels through home routers and office NAT, and when two hard NATs refuse to cooperate, a relay host forwards the encrypted traffic until a better path appears. Every host enforces its own firewall, default deny on all overlay traffic, with rules keyed to certificate groups, so laptops in the user-endpoint group can reach a server's web port while other groups cannot. Ordinary hosts need no inbound ports at all, and the same binary runs on Linux, macOS, Windows, phones, and FreeBSD, making the mesh feel identical at home, in a datacenter, or across three clouds. Unsafe routes can even pull an existing office subnet into the overlay, giving legacy hardware that will never run Nebula an address on the private network.

Credentials sitting forever in email threads and chat scrollback - Password Pusher solves that everyday security failure. Instead of pasting a password into Slack, you push it - a password, note, file, URL, or QR code - and share a unique one-time link that expires after a set number of views, a time limit, or both. Content is encrypted at rest with AES-GCM under a configurable master key, optionally guarded by a passphrase, and permanently deleted from the database the moment it expires; a retrieval-step option keeps URL-scanning bots from consuming views. Full audit logs record when each link was created and viewed (and by whom, with logins), and TOTP two-factor authentication can be required instance-wide. The delivery page is deliberately unbranded - no logos or confusing links for recipients - and the interface ships in 31 languages with light and dark themes. Automation runs through a JSON API (v2), an official CLI for pushing and expiring secrets from the terminal, a Chrome extension, and a catalog of third-party integrations. Apache-2.0 licensed Ruby on Rails, deployable via Docker, Kubernetes, or Helm, with SQLite or PostgreSQL storage - the sysadmin staple for sending credentials that clean up after themselves.

Starred by over 6,500 users on GitHub and trusted by organizations including Toyota, CTFd has been the leading open-source platform for hosting cybersecurity competitions since 2015, providing everything needed to run professional Capture The Flag events through a clean web-based administration panel without touching a database query. The framework supports both individual and team-based competitions with automatic tie resolution, configurable score freezing, and scoregraphs comparing the top teams with detailed progress tracking. Challenge creation offers static and regex-based flags, dynamic scoring that adjusts point values based on solve count, unlockable hints purchasable with points, file attachments uploaded to local storage or Amazon S3-compatible backends, and challenge attempt limits with automatic bruteforce protection. Version 3.8 introduced challenge logic fields controlling flag submission behavior with any, all, and team modes, integrated dynamic scoring into the standard challenge type, participant ratings and reviews on challenges, and admin-stored challenge solutions viewable after competition. The Markdown-based content management system enables custom pages for rules, FAQs, and resources, while SMTP and Mailgun integration handles email confirmation and password recovery. The plugin architecture supports custom challenge types, flag validators, and scoring algorithms, while the theme system provides complete visual customization. Import and export functionality preserves entire competition configurations for archival and reuse across events.

GCHQ open-sourced its "Cyber Swiss Army Knife", and CyberChef became the web app security analysts, incident responders, and CTF players reach for when data needs decoding, decrypting, or dissecting. Its interface is four panes: paste or drag input (files up to 2GB), search a categorized library of hundreds of operations, drag them into a recipe with arguments, and read the output. Operations span Base64, hex, and XOR encoding; AES, DES, and Blowfish encryption; classical ciphers from Caesar to Railfence; hashes and checksums; compression; regex and string extraction of IPs, domains, and URLs; timestamp conversion; and parsers for IPv6, X.509 certificates, and more. Recipes chain arbitrarily - convert from a hexdump then decompress, decrypt AES pulling the IV from the cipher stream, or let the Magic operation auto-detect several layers of nested encoding. Auto Bake re-runs the recipe live as input or arguments change, Step executes one operation at a time for debugging, and flow control (forks, subsections, registers) applies different operations to different parts of the data. Recipes save to files or share as URLs encoding the full pipeline. Crucially, CyberChef is entirely client-side JavaScript - nothing uploads anywhere - and self-hosting guarantees an unmodified copy inside your own network, where malware artifacts belong.

Backed by 9,000+ GitHub stars and developed by a Germany-based team with deep FIDO2 expertise, Hanko delivers the open-source authentication platform that replaces Auth0, Clerk, and Firebase Auth with a passkey-first architecture built on phishing-resistant WebAuthn credentials. The Go backend exposes both public and administrative HTTP APIs handling passkey registration and login, password authentication, email passcodes, TOTP-based MFA, security key verification, server-side sessions with remote revocation, and JWT issuing with configurable expiry and refresh policies. OAuth SSO connects Apple, Google, GitHub, Microsoft, and custom OIDC providers, while SAML Enterprise SSO integrates corporate identity providers for single sign-on across the organization. Hanko Elements provides framework-agnostic web components that embed complete onboarding, login, and user profile flows into any application with two lines of code, fully customizable via CSS variables and supporting i18n with custom translations. The JavaScript frontend SDK handles API communication, credential management, and session state for teams building custom authentication UIs without the pre-built components. Webhooks notify external services of authentication events including user creation, login, email verification, and password changes. Privacy-first design principles enforce data minimalism with user-deletable passwords and configurable identifier strategies supporting email-only, username-only, or combined approaches. Docker deployment starts the backend with PostgreSQL or MySQL, serving both APIs on configurable ports.

With 14,000 GitHub stars and 81 releases since March 2023, Stalwart is the most protocol-complete open-source mail server available — delivering JMAP, IMAP4rev2, IMAP4rev1, POP3, SMTP, CalDAV, CardDAV, and WebDAV from a single Rust binary that compiles to a memory-safe, zero-garbage-collection executable with predictable latency under load. The SMTP server implements DMARC, DKIMv2, DKIMv1, SPF, and ARC for complete message authentication with automatic DKIM key rotation, while transport security enforces DANE, MTA-STS, and SMTP TLS reporting to prevent downgrade attacks. Built-in spam filtering with statistical classifiers, DNS blocklists, and collaborative reputation databases eliminates the need for external Rspamd or SpamAssassin deployments. Encryption at rest protects stored messages with S/MIME or OpenPGP, and automatic TLS certificate provisioning via ACME supports TLS-ALPN-01, DNS-01, and HTTP-01 challenges without manual certificate management. The ManageSieve server enables server-side email filtering rules, while full-text search indexes message bodies and attachments for instant retrieval. Pluggable storage backends support RocksDB for embedded deployments, PostgreSQL, MySQL, and S3-compatible object storage for distributed architectures. LDAP and SQL-based authentication integrate with existing directory services, and the web administration panel manages domains, accounts, quotas, and DKIM keys. Security audited with memory safety guaranteed by Rust's ownership model.

A man-in-the-middle proxy you run on purpose, mitmproxy lets developers and testers inspect, edit, and replay HTTP and HTTPS traffic from any client. Point a browser, phone, or script at it and every HTTP/1, HTTP/2, HTTP/3, WebSocket, and TLS-protected connection appears as a flow you can open, search, and filter. Content views turn payloads from HTML to Protobuf into readable text. Intercept a request or response before it moves on, change its headers, body, or status by hand, then release it, or save the flow and replay it to the client or the server later. Map local and map remote rules answer requests with files or other URLs, while blocklists, anticache, sticky cookies, and proxy authentication cover routine test chores. Choose the interface that fits the job: a keyboard-driven terminal console, mitmweb in the browser with a Capture tab that sets up WireGuard devices with a QR code, or mitmdump for unattended logging in scripts. Proxy modes include regular, local capture, WireGuard, transparent, reverse, upstream, SOCKS5, and DNS. Addons written in Python add custom rewriting, recording, and automation. Teams use it for debugging, testing, privacy measurements, and penetration testing.

Comp AI turns the months-long slog of SOC 2, ISO 27001, HIPAA, and GDPR certification into a largely automated process by connecting to your existing infrastructure and continuously collecting the evidence auditors actually ask for. Point it at your AWS account, Google Cloud project, GitHub organization, or any of 580+ supported integrations, and autonomous agents pull configuration snapshots, access logs, encryption status, and policy compliance data on a recurring schedule so your compliance posture reflects reality rather than last quarter's manual export. The AI policy engine analyzes your tech stack, team structure, and risk tolerance to generate organization-specific policies for information security, access control, incident response, data retention, and vendor management; no two companies get the same boilerplate. An open-source device agent runs on employee machines checking disk encryption, firewall status, screen lock settings, password length, and antivirus presence around the clock, flagging failures the moment they occur instead of surfacing them during an audit. Built-in penetration testing agents scan your codebase and API endpoints for vulnerabilities like SQL injection and output audit-ready reports. The vendor risk management module scores third-party services and surfaces compliance gaps before they become findings. A public trust center lets prospects verify your compliance status directly, eliminating security questionnaire bottlenecks.

Dopbase keeps your application secrets out of scattered .env files and stores them, encrypted one by one, in a single self-hosted server you run as one file. You organize everything by project and environment, so the payment service has its own development, staging, and production values, and the same key can hold a different encrypted value in each place. Every secret is an individual record that can be updated, revealed, versioned, or rolled back without touching the others, and reading metadata never exposes a value. When an application starts, one command asks the server for an environment and injects exactly those values into the process, removing its own token before the child process runs. People sign in to the Admin UI with roles for root, admins, members, and even AI agents that can read metadata but change nothing. CI jobs and servers use runner tokens scoped to a single environment, so a staging credential can never read production. You can import and export .env files, edit secrets as a table or as raw env text, connect single sign-on through providers like Keycloak, and read an audit history of checks, reveals, and changes. Full-instance backups and the master key stay under your control on your own disk.

SpiderFoot is an open-source OSINT automation platform, replacing hours of manual reconnaissance with automated intelligence gathering across more than 200 data collection modules. The platform accepts ten distinct target types including IP addresses, domains, hostnames, network subnets, ASNs, email addresses, phone numbers, usernames, person names, and Bitcoin addresses, then feeds them through a publisher-subscriber event bus where each module's findings trigger downstream analysis automatically. SpiderFoot queries Shodan, VirusTotal, HaveIBeenPwned, AlienVault OTX, Censys, crt.sh, WHOIS databases, social media platforms, breach databases, and dozens more sources, with most modules requiring no API keys and many offering free tiers for those that do. The YAML-configurable correlation engine applies 37 pre-defined rules to identify relationships between discovered data points, flagging patterns like shared infrastructure, credential exposure, and domain reputation anomalies. Results export in CSV, JSON, and GEXF graph formats for integration with external analysis tools. TOR integration enables dark web searching, and SpiderFoot can invoke external tools including DNSTwist, Whatweb, Nmap, and CMSeeK for deeper technical assessment. The embedded web server delivers an intuitive dashboard for scan management, data visualization, and result exploration alongside a full command-line interface for scripted automation.

Your AI coding agent has your API keys in its environment and unrestricted network access, which means one prompt injection away from sending those secrets anywhere. Pipelock closes that gap by sitting as a proxy between your agents and every outbound connection, scanning the actual content of HTTP, WebSocket, MCP, and Agent-to-Agent traffic before it leaves your server. An 11-layer scanner pipeline checks every request against 62 credential patterns covering AWS, GCP, Azure, GitHub, OpenAI, Anthropic, SSH keys, and database URLs, then inspects every response for prompt injection using 29 detection patterns with six-pass normalization that catches base64-encoded, leetspeak, and whitespace-obfuscated payloads. The MCP proxy wraps any Model Context Protocol server (stdio, HTTP, or WebSocket) with bidirectional scanning that detects tool description poisoning and mid-session rug-pull changes via SHA-256 fingerprinting. Every scanning decision produces a cryptographically signed action receipt that third parties can verify offline without trusting the agent or the vendor. The Operator Console provides a web dashboard for reviewing evidence scorecards, receipt timelines, agent sessions, enforcement decisions, and fleet posture at a glance. Cross-request taint tracking catches slow-drip exfiltration attempts that spread a secret across multiple calls. Canary tokens plant synthetic secrets that trip alerts the moment an agent tries to exfiltrate them. Pre-built Prometheus metrics and a Grafana dashboard provide real-time visibility into traffic volumes and block rates.
