CalypsoAI vs SecureTom
LLM Policy Enforcement Platform. See how SecureTom compares on capabilities, compliance coverage, and accessibility.
About CalypsoAI
CalypsoAI offers LLM content moderation, policy enforcement, and automated red-team testing. F5 completed its acquisition of CalypsoAI in September 2025, and the technology is now sold as F5 AI Guardrails and F5 AI Red Team inside F5's application delivery and security platform. It focuses on controlling what goes into and comes out of large language models, which is useful for enterprises deploying customer-facing AI. However, the scope is narrow: runtime filtering and policy enforcement cover only one layer of AI security.

CalypsoAI limitations
- Focus is narrow: LLM runtime guardrails and policy enforcement
- Does not cover infrastructure security, model training risks, or data pipeline vulnerabilities
- Red-teaming is automated prompt testing, with no human-led adversarial testing service
- Compliance coverage is limited to content-related risks
- Now part of F5 and positioned for large enterprises, not smaller teams
What SecureTom adds
- Full-stack AI security that goes beyond content filtering.
- Human-led red-teaming by the BeyondScale team that simulates real adversarial scenarios, not just automated policy checks.
- Compliance readiness across multiple frameworks: EU AI Act, NIST AI RMF, ISO 42001, SOC 2, HIPAA.
- Independent platform that works with any cloud provider.
- Practical remediation guidance with engineering-level detail, not just policy violation alerts.
Frequently Asked Questions
No. F5 completed its acquisition of CalypsoAI in September 2025. The products now ship as F5 AI Guardrails and F5 AI Red Team within F5's application delivery and security platform. Teams that chose CalypsoAI as a standalone vendor are now buying from F5, which is one reason buyers look for a CalypsoAI alternative.
For runtime guardrails, the common alternatives are Lakera (now part of Check Point), Prompt Security (now part of SentinelOne), Cisco AI Defense (built on Robust Intelligence), and Palo Alto Networks Prisma AIRS (built on Protect AI). HiddenLayer remains independent and focuses on model-layer detection. SecureTom is a different kind of alternative: instead of filtering traffic at runtime, it scans and tests your AI application for vulnerabilities, with human-led red-teaming available from the BeyondScale team.
CalypsoAI focuses on LLM content moderation, policy enforcement, and output monitoring. It controls what goes into and comes out of language models, and adds automated red-team testing of those models. It does not cover infrastructure security, model training risks, human-led adversarial testing, or broader compliance mapping.
CalypsoAI specializes in controlling LLM inputs and outputs through content policies. SecureTom takes a broader approach: it tests the entire AI stack, from the model's behavior under adversarial conditions to the infrastructure it runs on. Content filtering is one part of AI security, but it is not the whole picture.
Yes. SecureTom scans test LLM outputs for data leakage, hallucination risks, and policy violations. They also test for prompt injection, jailbreaking, and other adversarial techniques that CalypsoAI's automated filters may not catch.
Yes. SecureTom assesses your full AI security posture, including the areas CalypsoAI does not cover: infrastructure, model training, data pipelines, and human-led adversarial testing. Reports are designed to be actionable, with specific technical recommendations your engineering team can implement.
Yes. SecureTom is not tied to any cloud provider. It assesses AI systems on AWS, Azure, GCP, on-premises, or hybrid environments.
