Cymulate

What the company sells

Cymulate sells the Cymulate Platform, which turns validation into a continuous, adaptive process of agentic cyber defense engineering. Cymulate says manual testing and control updates can take days to adapt to new threats. With Vero AI, Cymulate says it understands new threats, tailors validation to the customer's environment and turns findings into prioritized actions and automated security control updates.

Cymulate says its threat library has full MITRE ATT&CK coverage. The platform includes a daily feed of the latest threats with a 24-hour SLA for updated attack simulations for new US Cert threat advisories. Cymulate safely simulates real-world attack techniques across endpoints, networks, email, web gateways and cloud environments, with integrations to the controls and SIEM to prove both prevention and detection. Testing results create scorecards and benchmarks for security controls, MITRE ATT&CK coverage and specific threats. Cymulate combines breach and attack simulation, exposure validation and actionable remediation guidance in a single platform.

For exposure management, Cymulate says customers can automate validation as part of a continuous threat exposure management program. Cymulate lets customers push vendor-specific threat mitigation and behavior rules for immediate prevention or detection. Cymulate Auto Mitigate deploys relevant IoCs to security controls after teams follow remediation guidance for validated gaps. The Cymulate + Bitsight integration creates a closed loop between adversary intelligence and continuous exposure validation. In the Cymulate Platform, Bitsight provides relevant adversaries, campaigns, ransomware groups, APTs, TTPs, IoCs and targeting trends that are then used to focus testing and validation workflows.

On detection, Cymulate Detection Studio automates SIEM rule validation and detection tuning against real-world attacks. Cymulate says it transforms detection engineering from a manual, resource-intensive process into a continuous, automated lifecycle. Vero AI maps rules to attack scenarios, tests detection performance, identifies gaps and recommends or generates new rules. Cymulate generates Sigma rules and vendor-specific detection rules from validated gaps and provides guided tuning for the rules customers already have. Once deployed, rules are retested against the original attack scenario to confirm they improved detection. Cymulate simulations are production-safe: they reproduce the techniques and behavior of real attacks without executing actual malicious payloads or causing damage to systems or data.

Cymulate says it is built for security teams that need continuous validation across their environment, including security operations, detection engineering, red teams and exposure management teams. Cymulate says it supports organizations of all sizes, from mid-market to enterprise, especially those with complex or evolving security stacks. Cymulate says it empowers executives, security operations and the whole security program to continuously prove, prioritize and adapt security for specific threats and exposures.

Cymulate was founded by former IDF intelligence officers and cyber researchers. Cymulate says its platform runs on a private AWS tenant engineered for isolation, high availability, and redundancy across multiple regions. Cymulate does not collect or store sensitive Personal Identifying Information or PCI-DSS cardholder data. Cymulate states that data stored in databases and AWS is encrypted with AES-256. Cymulate has independent external auditor attestation across the Security, Availability, Confidentiality and Privacy Trust Services Criteria, and a public SOC 3 report.^{[1][3][5][6][7][8]}
