IT managed services and managed security services provider Abacus has achieved CREST accreditation for its penetration testing services.

The independent Council for Registered Ethical Security Testers evaluated Abacus’ approach, including team expertise, client data handling, quality assurance and staff training, alongside client references.

Abacus’ services assess clients’ attack surfaces and security posture by simulating malicious intrusions across cloud, network and server infrastructure. Its new adversarial simulation service combines AI technology with expertise for technically rigorous and contextually intelligent testing.

Tom Cole, senior managing director, EMEA at Abacus, said: “In an age of relentless cyberattacks and constantly evolving regulatory requirements, it is crucial our clients can trust that they are working with a top-tier partner. The CREST accreditation validates our alignment with global best practices, providing our clients in regulated industries, like financial services and healthcare, with verification and assurance of our Red Team’s strict technical rigour.”

The accreditation, completed between October 2025 and February 2026, requires annual renewal to maintain the demonstrated standards.
