Features and specs

What each product offers, as listed by its team.

KeePass 7 features
ContractShield.dev 12 features
  • Open Source
    KeePass is open-source software, which means its source code is publicly available for review. This ensures transparency and allows for independent security audits.
  • Free
    KeePass is completely free to use. There are no subscription fees or one-time purchase costs, making it accessible to everyone.
  • Strong Encryption
    KeePass uses strong encryption algorithms (AES-256, ChaCha20) to securely store passwords, making it very difficult for unauthorized users to access the stored data.
  • Cross-platform Availability
    KeePass supports multiple operating systems including Windows, macOS, Linux, and has a variety of compatible third-party apps for mobile platforms like Android and iOS.
  • Offline Storage
    KeePass stores the password database locally on your device rather than in the cloud, reducing the risk of remote hacks or breaches.

Questions & Answers

As answered by people managing KeePass and ContractShield.dev.

What makes your product unique?

ContractShield.dev's answer:

ContractShield is the only open-source middleware that enforces your OpenAPI contract at runtime — not just for documentation, but as a security policy.Most API security tools either scan for vulnerabilities (shift-left testing) or inspect payloads for known attack patterns (WAFs). ContractShield does neither. It sits inside your application and validates every request against what your API should do, not what attacks look like.

  • Deny-by-default: if an endpoint isn't in your OpenAPI spec, it doesn't exist
  • Schema-enforced auth: missing authentication is blocked regardless of whether your app forgot to check
  • CEL invariants: custom business rules that execute on every request
  • Zero infrastructure changes: standard middleware, 5-minute integration

The result: it catches business logic attacks — authentication bypasses, BOLA/IDOR, parameter tampering, prototype pollution — that produce perfectly valid HTTP requests every WAF in the world allows through.

Why should a person choose your product over its competitors?

ContractShield.dev's answer:

  • vs. WAFs (Cloudflare, AWS WAF, Reblaze): WAFs can't see business logic. A GET /api/v1/users/456 from an attacker looks identical to a legitimate request. ContractShield understands the contract and blocks it.

  • vs. API security platforms (Salt, Noname, Traceable): These are enterprise-grade, agent-based, and expensive. ContractShield is lightweight middleware you install in 5 minutes with zero infrastructure changes.

  • vs. API testing tools (Akto, Escape.tech, Pynt): These find vulnerabilities before production. ContractShield blocks attacks in production — they're complementary, not competing.

  • Open source core (Apache 2.0): No vendor lock-in, fully auditable code, free for production use. Security certifications include OWASP ASVS Level 1, OpenSSF Scorecard, and SLSA Build Level 1 provenance.

  • Multi-platform from day one: Node.js, Python, and Java — covering ~80% of the API development market.

How would you describe the primary audience of your product?

ContractShield.dev's answer:

  • Backend developers and API engineers building REST APIs who want runtime protection without adding infrastructure complexity

  • DevSecOps teams looking to enforce API contracts as security policy in CI/CD and production

  • CTOs and engineering leads at startups and mid-market companies who need API security beyond their WAF but can't justify six-figure enterprise platform contracts

  • Regulated industries (fintech, healthtech, identity verification) where API business logic protection is a compliance requirement

  • Teams already using OpenAPI specifications — ContractShield turns their existing documentation into an active security layer

What's the story behind your product?

ContractShield.dev's answer:

ContractShield was born from years of penetration testing. Running API security assessments for clients, we kept finding the same pattern: organizations had invested in WAFs, API gateways, and network security — yet their APIs were wide open to business logic attacks.

Authentication bypasses. BOLA/IDOR. Parameter tampering. Prototype pollution. Every single one produced clean, valid HTTP requests that sailed through every layer of infrastructure security. The vulnerability wasn't in the payload — it was in the logic.

We realized the gap: infrastructure tools protect the transport layer, but nobody was protecting the contract layer — the actual business rules that define what an API should and shouldn't do.

So we built ContractShield as middleware that reads your OpenAPI specification and enforces it at runtime. Your API contract becomes your security policy. If it's not in the spec, it's blocked. If auth is required, it's enforced. If the schema says no, it means no.

We open-sourced the core under Apache 2.0 because API security shouldn't be a luxury reserved for enterprises with six-figure budgets. We continue to offer Penetration Testing as a Service (PTaaS) alongside the product — because automated protection and expert assessment together provide the strongest security posture.

Which are the primary technologies used for building your product?

ContractShield.dev's answer:

  • TypeScript/Node.js — Core middleware engine and npm packages (@cshield/core, @cshield/pro)
  • Python — FastAPI and Flask middleware adapters (PyPI: contractshield)
  • Java/Spring Boot — Spring Boot starter for enterprise Java APIs (Maven Central)
  • OpenAPI/Swagger — Contract parsing and schema validation engine
  • CEL (Common Expression Language) — Policy engine for custom business rule invariants
  • GitHub Actions — CI/CD, CodeQL security scanning, SLSA provenance, automated publishing
  • Astro — Marketing site and documentation

Who are some of the biggest customers of your product?

ContractShield.dev's answer:

ContractShield PTaaS (our own penetration testing platform runs on ContractShield). Privacy is our moto, contact us for more information.
