About Siemba
Siemba provides offensive security testing through a platform and expert services. It sells to security teams that need to test faster than they can hire. The company offers autonomous penetration testing software that customers run themselves, plus expert-led penetration tests delivered by in-house certified testers. It also provides attack surface mapping and vulnerability assessment. The platform covers web apps, APIs, networks, cloud, mobile, and AI systems such as LLM apps, AI agents, and MCP servers. Siemba says it differs by combining continuous automated testing with manual depth, and by retesting every fix to prove closure. It serves enterprises, government clients through partners, and firms needing compliance evidence for standards like PCI DSS, SOC 2, ISO 27001, and HIPAA.
