## 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

## Mindgard

Mindgard is an AI security platform that approaches protecting AI systems the way an attacker would. Instead of starting with a checklist of prompts, it begins with agent-native reconnaissance: profiling the models, agents, tools, instructions, permissions and behaviours that make up an AI system, so it can identify the attack paths most likely to cause real damage. That reconnaissance is fed by vulnerability intelligence drawn from the company's own published disclosures.

The platform spans the full security loop. Recon surfaces what an AI deployment can actually do; red teaming continuously tests agents and systems against evolving attacks; assessment validates which weaknesses are genuinely exploitable and quantifies their impact; runtime protection and remediation guidance help teams close gaps and verify that defences hold as the system changes. This matters because AI behaviour shifts with every model update, prompt change or new tool integration, which makes one-off testing insufficient.

Mindgard originated from more than a decade of AI security research at Lancaster University and says its technology has been behind 175+ publicly disclosed vulnerabilities in prominent AI systems. It is designed to slot into existing engineering workflows through APIs, CI/CD pipelines and Burp Suite integration, so AI security assessment can run before deployment and continuously in production rather than as a periodic external exercise.

**Pricing & Plans:** Mindgard does not publish public pricing. Plans are quoted based on scope, deployment model and enterprise requirements. Contact the team for a demo and custom quote.

- **Attacker-style AI reconnaissance:** Agent-native reconnaissance maps models, agents, tools, instructions, permissions and behaviours the way an attacker would before launching attacks.
- **Continuous AI red teaming:** Continuous, adaptive testing of AI agents and systems against evolving attack techniques, rather than one-off audits.
- **Proprietary vulnerability intelligence:** Findings are backed by a knowledge base built from more than 175 publicly disclosed AI vulnerabilities across major AI systems.
- **Remediation and runtime protection:** Runtime protections and remediation guidance help close defensive gaps and verify that fixes actually hold.
- **Governance and compliance support:** Risk reduction, evidence and reporting aligned to AI policies and governance requirements, keeping AI compliant as it changes.

**Strengths:** Attacker-led methodology focuses on provably exploitable risk rather than generic prompt noise; Backed by a decade of Lancaster University AI security research and 175+ disclosures; Covers recon, red teaming, assessment, remediation and runtime protection in one platform; Integrates with CI/CD, APIs and Burp Suite for continuous assurance

**Limitations:** Requires a sales conversation; no transparent public pricing; Some capabilities overlap with other AI security vendors, so evaluation takes care; Fully realising value assumes integration into CI/CD and security workflows
