Abacus Earns CREST Accreditation for Penetration Testing Services
Abacus, a global provider of IT Managed Services (MSP) and Managed Security Services (MSSP) for highly regulated sectors, has announced that its penetration testing services have earned accreditation from the Council for Registered Ethical Security Testers (CREST).
This globally recognised certification confirms that Abacus conducts penetration testing in line with stringent technical, ethical, and legal standards. The independent CREST assessment—trusted by regulators—reviewed the company’s methodologies as well as the skills and qualifications of its team.
To achieve accreditation, Abacus was required to demonstrate robust practices in areas such as client data management, quality assurance, and control processes. The company also provided evidence of continuous professional development for its staff and submitted multiple client references validating its professionalism, depth of testing, and overall service quality.
With CREST validation, Abacus strengthens confidence among clients and prospects, assuring them that its services align with industry-leading security practices and that advanced penetration testing is delivered safely and effectively.
At a time when only a limited number of MSPs meet this high cybersecurity benchmark, the accreditation further establishes Abacus as a trusted global provider of penetration testing services, dedicated to safeguarding sensitive data and ensuring regulatory compliance.
Tom Cole, Senior Managing Director for EMEA at Abacus, commented that in today’s environment of persistent cyber threats and evolving regulations, clients need assurance that they are partnering with a top-tier provider. He added that the CREST accreditation confirms alignment with international best practices and offers clients in regulated industries—such as finance and healthcare—confidence in the technical rigor of Abacus’ Red Team operations.
Abacus’ penetration testing services enable organisations to better understand their potential attack surface and overall security posture by simulating real-world cyberattacks. This involves replicating the actions of malicious actors attempting to exploit vulnerabilities across cloud systems, networks, and server environments.
In addition, the company now provides an advanced adversarial simulation service that blends agentic AI capabilities with the expertise of experienced Red Team professionals. This combined approach ensures testing that is both highly precise and context-aware.
The CREST accreditation process for Abacus took place between October 2025 and February 2026. To maintain this status, the company will undergo annual renewals to ensure continued adherence to the required standards.
