Abacus has announced that it has achieved Council for Registered Ethical Security Testers (CREST) accreditation for its penetration testing services.
The internationally-recognised CREST accreditation verifies penetration testing in accordance with the highest technical, ethical and legal standards.
Backed and trusted by regulators, the company said that the rigorous process conducted by the independent body evaluated Abacus’ penetration testing approach, including the expertise and qualifications of the team.
In order to pass the auditing process, evidence of client data handling, quality control and assurance processes were required.
Abacus said that it also had to demonstrate an ongoing professional training programme for staff and provide numerous references from clients, attesting to its professionalism, testing depth and quality.
Abacus’ successful completion of CREST validation gives customers and prospects confidence that they are working with a provider that meets security best practices and can be trusted in delivering advanced penetration tests securely.
In a market where very few MSPs have achieved this benchmark for cybersecurity quality and professionalism, the company highlighted that it reinforces Abacus’ position as a leading global provider of penetration testing services, committed to protecting customers’ sensitive data and maintaining compliance.
Tom Cole, Senior Managing Director, EMEA at Abacus says: “In an age of relentless cyber-attacks 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 rigor.”
Abacus’ sophisticated penetration testing services help clients understand their attack surface and defence-in-depth security posture.
They do this by emulating a malicious adversary attempting to hack into the organisation by exploiting vulnerabilities across their cloud, network and server infrastructure.
Abacus stated that it now also offers an adversarial simulation service which combines the precision and scalability of agentic AI technology with the strategic insight of senior Red Team penetration testers.
This hybrid model ensures that every test is both technically rigorous and contextually intelligent.
The CREST accreditation process for Abacus was carried out by CREST between October 2025 and February 2026.
The accreditation will need to be renewed annually to ensure that the standards Abacus has demonstrated in penetration testing are continuously upheld.
