Best alternatives to Privacy Mask in 2026
Pasting a screenshot into ChatGPT or Claude to ask 'what's wrong with this UI' or 'help me debug this' is a common habit — but that screenshot often has a phone number, an ID card, or a stray API key visible in it, and once it's sent, it's sent. Privacy Mask catches that before it happens: it scans a screenshot locally, finds anything sensitive, and blurs or blocks it out automatically. Privacy Mask is a free, open-source, MIT-licensed tool that detects over 40 categories of sensitive data — phone numbers, national ID card formats from 15+ countries, financial data, and API keys — using a combination of named-entity recognition and regex pattern matching, backed by dual OCR engines (Tesseract and RapidOCR) to read text embedded in images. Everything happens 100% locally and offline, so the original unredacted screenshot never has to leave your machine, and it integrates with 20+ AI coding platforms so it can sit in your existing workflow rather than requiring a separate manual step.

#1
- ✓ Transport-layer injection — the key never enters agent memory at all
- ✓ Six auth injection styles cover most real-world API shapes
#2
A free firewall for AI agents that browse the web — it strips hidden prompt-injection attacks out of pages before the agent ever reads them.
fireclaw.app
- ✓ 4-stage layered defense against prompt injection
- ✓ 'No bypass mode' prevents accidentally shipping without protection
#3
Getting SOC 2 or ISO 27001 certified means proving, with evidence, that your policies match reality — normally a spreadsheet nightmare or a $10k-a-year SaaS subscription (Vanta, Drata). Openlane does the same evidence-collection and tracking job as open-s
theopenlane.io
- ✓ Free, open source (Apache 2.0), self-hostable — real alternative to paid compliance SaaS
- ✓ Covers 12+ frameworks including SOC 2, ISO 27001, GDPR, HIPAA
#4
Takes the list of every open-source component your software depends on (its SBOM) and tells you which ones have known security holes, then gives you a web dashboard to triage and report on them — rather than making you cross-reference vulnerability databa
github.com
- ✓ Free, open source, self-hosted SBOM triage and reporting tool
- ✓ Supports multiple SBOM formats including embedded-focused Yocto CVE
#5
A password manager that never talks to the internet at all — your vault, encrypted with AES-256, lives only on your Windows PC, so there's no cloud account to breach and no subscription to pay, at the cost of syncing to your phone.
github.com
- ✓ Free, open source, fully offline — no cloud account or subscription
- ✓ Modern encryption (AES-256-GCM + Argon2id key derivation)
#6
When a suspicious IP address, file, or link crosses an analyst's desk, checking it properly means querying a dozen different services (VirusTotal, Shodan, MISP...) one by one. IntelOwl does all those lookups at once through a single dashboard, for free.
github.com
- ✓ Free, open source, backed by a real security vendor (Certego) and The Honeynet Project
- ✓ Combines internal analysis tools with 50+ external threat-intel integrations
#7
A self-hosted Google Drive/Dropbox alternative where files are encrypted in your browser before they ever reach the server — so even the machine storing your files never sees what's actually in them.
github.com
- ✓ True client-side (browser) end-to-end encryption — server never sees plaintext
- ✓ Modern, quantum-resistant key wrapping (X25519 + ML-KEM-768)
#8
A security team running five different scanners (one for containers, one for code, one for dependencies...) ends up with five different spreadsheets of findings, half of them duplicates. DefectDojo pulls all of that into one place, removes the duplicates,
defectdojo.com
- ✓ Mature, widely adopted (4,900+ GitHub stars, 38M+ downloads)
- ✓ Aggregates and deduplicates findings from 500+ security tools
#9
A free, open-source vulnerability scanner that combines fast, deterministic security checks with an optional AI agent that plans and triages findings on its own — built for penetration testers and security teams who want automation without losing precisio
github.com
- ✓ 323 scanner modules (207 active, 116 passive) covering the OWASP Top 10
- ✓ AI-driven Agentic Scan mode — can write custom extensions and catch logic bugs (IDOR/BOLA)
#10
A free, open-source, experimental framework from security firm Hadrian that turns a coding AI assistant like Claude Code or Cursor into a structured vulnerability-research team — complete with checkpointed progress and OWASP/MITRE-aligned expert agents.
github.com
- ✓ Structured methodology (recon, scoped scenarios, independent triage) instead of an unguided AI prompt
- ✓ 12 expert agents aligned to OWASP/MITRE
#11
A free, open-source OWASP project that scans your project's lockfile for known vulnerabilities and hands you copy-and-run fix commands — dependency security that lives in your terminal instead of buried in a CI dashboard you check once a week.
github.com
- ✓ Local, offline scanning with copy-and-run fix commands
- ✓ Distinguishes direct vs transitive dependencies to target the real source of risk
#12
A free, open-source, self-hosted alternative to Google Authenticator — manage and generate your two-factor login codes from a web app you run yourself, on any device with a browser, instead of being tied to one phone.
github.com
- ✓ 2FA codes reachable from any browser, not tied to a single phone
- ✓ Supports TOTP, HOTP and Steam Guard, RFC 4226/6238 compliant
