Kolega vs Hostile Review
An honest comparison. One finds vulnerabilities and auto-generates fix PRs — the other deploys 108 adversarial agents to attack your code from every angle.
Kolega is a code remediation engine — it scans for security vulnerabilities and automatically generates merge-ready pull requests with fixes and tests. Think of it as a security scanner that also does the repair work.
Hostile Review is an adversarial code audit — 108 specialized agents that assume your code is broken and prove where. Think of it as deploying a red division against your codebase before an attacker does.
| Kolega | Hostile Review | |
|---|---|---|
| Approach | SAST/SCA + auto-remediation PRs | Adversarial multi-agent AI audit |
| Detection Method | Static analysis + semantic logic + AI validation | 108 AI agents reasoning adversarially |
| Auto-Fix | ✓ Merge-ready PRs with tests | Remediation guidance (no auto-PRs) |
| When It Runs | Scheduled, on-demand, or PR-triggered | On-demand scans |
| What It Scans | Source code + dependencies (SBOM/SCA) | Full codebase or selected files |
| Alert Noise | 90% reduction (logical grouping) | Consensus deduplication across agents |
| Pricing | Free tier + $99–$499/month | Pay per scan, no seats |
| Free Tier | ✓ 4 deep scans/mo (no PRs) | ✓ Demo scans (20 files) |
| Scope Beyond Security | Security-focused only | 14 categories (security, perf, compliance, arch, AI, a11y, i18n, cloud...) |
- Find-and-fix in one step — doesn't just report vulnerabilities, it generates merge-ready PRs with code fixes and tests included
- Smart alert grouping — 50 similar issues become 1 ticket, reducing noise by up to 90%
- Two-tier detection — standard SAST/SCA plus a proprietary deep scan layer for semantic logic flaws with zero overlap
- Cross-service taint tracking — follows data flow across service boundaries to find second-order injection and deserialization flaws
- Memory architecture — remembers alert status globally, so suppressed issues stay suppressed across scans
- Priority intelligence — ranks findings by actual exploitability, not just CVSS score
- Proven track record — 225 vulnerabilities found across 45 major open-source projects, 90%+ acceptance rate on submitted fixes
- Scale beyond any scanner — 108 agents each attack from a different angle, then findings are deduplicated and consensus-ranked. From red team to red division
- 14 review categories — goes far beyond security: performance, architecture, compliance (GDPR/HIPAA/PCI), AI & systemic risk, accessibility, i18n, cloud infrastructure, data pipelines
- Cross-file attack chains — finds vulnerabilities that span multiple files and components, where the issue isn't in any single file
- AI & LLM security — 7 dedicated agents for prompt injection, model poisoning, denial-of-wallet — categories most scanners don't cover at all
- Compliance-grade depth — dedicated agents for GDPR, HIPAA, PCI-DSS, SOX, and SOC2 requirements
- No per-seat pricing — one scan costs the same whether you have 2 developers or 200
- Granular control — choose which agents run, at which quality tier, on which files. Live cost estimate before you scan
| Category | Kolega | Hostile Review |
|---|---|---|
| Injection Attacks (SQL, XSS, Command) | ✓ Including second-order | ✓ 6 dedicated agents |
| Auth & Access Control | ✓ IDOR, auth bypass | ✓ 5 dedicated agents |
| Secrets & Key Exposure | ✓ Tier 1 detection | ✓ Vault + Gatekeeper + Specter |
| Dependency Vulnerabilities | ✓ SBOM + SCA | ✓ Supply + Provenance agents |
| Deserialization & Race Conditions | ✓ Deep scan | ✓ Concurrency + data flow agents |
| Auto-Generated Fix PRs | ✓ With tests | ✗ Remediation guidance only |
| Cryptography Review | ✗ | ✓ Cipher + Entropy agents |
| Performance & Scaling | ✗ | ✓ Turbo + Shard + Profiler |
| Architecture & Design | ✗ | ✓ Blueprint + Typesmith |
| Compliance (GDPR, HIPAA, PCI) | ✗ | ✓ 6 compliance agents |
| AI & LLM Security | ✗ | ✓ 7 AI agents (prompt injection, model poisoning, denial-of-wallet) |
| Cloud & Infrastructure | ✗ | ✓ Spend + Elastic + Lambda + Provision |
| Accessibility & i18n | ✗ | ✓ Accessible + Rosetta + Glyph |
Kolega finds and fixes. It scans for security vulnerabilities, generates code patches, writes tests, and opens PRs you can merge. The goal is zero manual remediation work.
Hostile Review finds what others miss. 108 AI agents reason adversarially about your code across 14 categories — security, performance, compliance, architecture, AI risk, and more. The goal is complete visibility before it ships.
Kolega is a surgeon: precise, targeted, focused on security. Hostile Review is a full-spectrum assault: wide, deep, and deliberately hostile.
