About WorkNest

WorkNest provides cyber security services through its Secure division. It sells penetration testing, exposure management, advanced security testing, security operations and compliance support. The work covers APIs, web and mobile apps, cloud, enterprise and wireless networks, plus large language models. It also offers red teaming, social engineering and security awareness training. GuardNest is its exposure management offering. The GuardNest platform centralises vulnerability data, insights and remediation in one place. Continuous vulnerability scanning gives ongoing visibility of risks across an operational environment. Penetration testing can be added when needed, so the service scales with requirements. Security operations include cyber incident response, digital forensics and managed SIEM, with continuous monitoring and rapid response. Compliance services cover SOC 2, ISO 27001, ISO 42001, GDPR and an outsourced DPO. The company serves organisations in the UK and US.
