## Hacktron

Hacktron is an AI-native cybersecurity platform built around the idea that offensive security should run continuously rather than in occasional annual engagements. It bundles three products under one roof: Red for ongoing adversary-style testing of your entire attack surface, Whitebox for deep white-box penetration testing driven by source-code analysis, and Review for automated security checks on every pull request.

The approach leans on AI agents that read actual code, reproduce issues, and attempt to demonstrate exploitability. This matters because traditional static analysis tools generate large volumes of theoretical findings that security teams must triage manually. Hacktron's stated position is to report only what it can prove is exploitable, with remediation guidance attached, so engineers spend their time on real risk.

Reported customers are engineering and product-security teams, including CTOs and compliance officers who need audit-ready evidence for SOC 2 and ISO 27001. The company has publicly announced a partnership with OpenAI to find vulnerabilities in its systems, and it publishes security advisories, a changelog, and open-source tooling. Deployment ranges from a self-serve Review trial to on-premises enterprise installations for sensitive environments.

**Pricing & Plans:** Freemium with custom enterprise tiers. Hacktron Review Pro starts at about $40 per developer per month including 50 pull requests per developer, with $1 per additional PR, and is free for open source. Whitebox pentests are priced per engagement, roughly $50 to $25,000 depending on scope (about $500 per 100,000 lines of code). Red and enterprise deployments are quote-based.

- **Continuous red teaming:** Hacktron Red continuously attacks your entire organization the way a real adversary would, then shows you the breach path and helps close it.
- **Machine-speed white-box pentests:** Hacktron Whitebox reads your source code, proves each finding in a sandbox or against your deployed app, and produces an audit-ready report for SOC 2 or ISO 27001.
- **Pull request security review:** Every pull request is checked with your whole codebase as context, so issues are caught before they merge into main.
- **Exploitability-based findings:** Only findings that can be shown to be exploitable are reported, verified rather than predicted.
- **API, MCP, and automations:** An API, MCP server, and automation layer let teams wire Hacktron into existing CI/CD and security workflows.

**Strengths:** Combines red teaming, white-box pentesting, and PR review in a single platform; Focuses on verified, exploitable findings instead of raw theoretical alerts; Transparent published pricing for Review and Whitebox tiers; Free for open source, with self-serve trial and API/MCP access

**Limitations:** Red teaming and enterprise deployment require a sales conversation; Whitebox pentest pricing scales with codebase size, which can get expensive; Best value requires integrating it into your existing CI/CD and code review flow

## Janus (now Kairos)

Janus began as a platform for battle-testing and improving AI agents, and the company has since rebranded to Kairos (withjanus.com now redirects to withkairos.co, and the site footer still credits 'Janus AI, Inc.'). Today Kairos positions itself as the AI deployment layer for critical industries — turning frontier models into specialized, reliable systems for enterprises in regulated sectors.

The core problem it addresses is trust. Off-the-shelf models are probabilistic and do not know your internal policies, so Kairos learns your rules from the people who actually run the process and deploys agents that hit very high accuracy thresholds. Evaluation, simulation and continuous learning sit at the heart of that loop: teams can build custom evaluations, simulate realistic scenarios, and detect failure classes such as hallucinations, rule violations and broken tool calls.

Deployment happens inside your own environment, so sensitive data never leaves your walls and accuracy compounds over time. Because the underlying intelligence is built on your processes and regulations, it becomes an asset you own rather than a rented generic model. The platform targets enterprises where high-stakes work leaves no margin for error.

**Pricing & Plans:** Contact for pricing. Kairos/Janus does not publish public plan tiers; pricing is arranged through a demo and tailored to enterprise deployment needs.

- **Custom agent evaluations:** Build bespoke test suites that mirror your real workflows so agents are measured against your rules, not generic benchmarks.
- **Hallucination & rule-violation detection:** Automatically flag fabricated answers, policy breaches and unsafe outputs before an agent goes live.
- **Tool-call failure detection:** Catch broken API calls, malformed arguments and failed agent tool usage that would silently break automations.
- **Simulation-based battle testing:** Run agents through realistic simulated scenarios to surface weaknesses without exposing real customers or data.
- **Private, sovereign deployment:** Deploy inside your own environment so data never leaves your walls and the resulting intelligence stays yours.

**Strengths:** Purpose-built for agent evaluation rather than generic LLM benchmarking; Detects concrete failure classes: hallucinations, rule violations and tool-call errors; Supports private, in-environment deployment for regulated industries; Custom evaluations tailored to your own processes and policies

**Limitations:** No public pricing or self-serve tier — you must talk to sales; Rebranding from Janus to Kairos can make documentation and links harder to follow; Best value for large enterprises; overkill for small hobby projects
