Backed by the UK’s National Cyber Security Centre, Cyber Essentials Plus is the highest level of assurance in the Cyber Essentials scheme. It involves rigorous, independent testing to verify that an organisation’s systems are well protected against the most common cyber threats. For TSO, maintaining this certification year after year is a clear reflection of our commitment to resilience, integrity and trust.
Built-in security for the services that matter
We work with government bodies, regulators and standards organisations to make complex information easier to find, use and understand - for people, and for machines. The services we support are often vital, public-facing and high-trust. Whether it’s publishing legislation or enabling access to health and safety guidance, security must be a constant - not an afterthought.
Achieving Cyber Essentials Plus means our digital platforms, IT systems and working practices are continuously tested and improved to defend against potential threats. We back this with a full suite of accreditations, including ISO/IEC 27001, Cyber Essentials Plus, and PCI DSS, and maintain a proactive approach to security monitoring, risk detection and incident prevention.
What it means for our clients
For the organisations we work with, confidence in how we manage data, digital content and technology is essential. Retaining Cyber Essentials Plus helps our clients demonstrate they are partnering with a supplier that meets government-backed security standards, protects sensitive and mission-critical content, delivers secure digital services at scale and has resilience built into every layer of delivery
It’s also a key part of enabling innovation. From AI-readiness to accessibility compliance, security supports the trusted platforms that public sector users and citizens can depend on.
Securing trust and maintaining it
Security isn't a one-time achievement - it’s a mindset that shapes how we work every day. For TSO, this means embedding best practice across our teams and systems, and being externally tested to prove it.
In a world where digital trust is more important than ever, we’re proud to offer our clients the peace of mind that comes with knowing their services are in safe hands.
