Trustwave

Trustwave has established itself as a significant managed security services provider since 1995, operating from Chicago with a global presence across 96 countries. Now part of LevelBlue following its 2025 acquisition, Trustwave brings over 2,000 security professionals and operates multiple Security Operations Centers worldwide. The company's SpiderLabs research team provides award-winning threat intelligence that powers their detection capabilities.

The company offers comprehensive managed security services including MDR, co-managed SOC (SIEM), penetration testing, digital forensics and incident response, email security, and database security. Trustwave has historically maintained strong capabilities in PCI DSS compliance services, though they divested this business unit in 2021 to focus on core MDR and MSS offerings. Their managed services approach emphasizes 24/7 monitoring with support for 360+ telemetry sources.

Trustwave's SpiderLabs team has earned recognition for discovering significant threats including GoldenSpy malware and critical SolarWinds vulnerabilities. However, the company has faced challenges including a controversial 2011 certificate authority incident and a 2014 lawsuit related to the Target breach, which resulted in some reputational damage. Customer reviews reflect mixed experiences, with some praising technical expertise while others cite customer service concerns.

For organizations requiring compliance-focused security services with robust threat intelligence, Trustwave offers proven capabilities backed by deep industry experience. The recent LevelBlue acquisition may bring enhanced resources and expanded service offerings, though integration outcomes remain to be seen. Best suited for organizations prioritizing managed security services with strong compliance requirements.
