Security As-a-Service

Entasis Partners delivers specialist security capability across three disciplines: security architecture, identity, and offensive security. We work at enterprise and solution level, embedding experienced practitioners who combine strategic thinking with hands-on delivery. No broad generalist teams - the right expertise, where it is needed, when it is needed.

  • Security Architecture & Design
  • Cyber Security Strategy
  • Security Governance, Risk & Compliance
  • Cloud Security
  • Identity & Access Management
  • Security Operations & Incident Response
  • Penetration Testing
  • Zero Trust Architecture

Our security practice sits alongside our architecture and transformation capabilities, giving clients a single partner for complex, multi-domain programmes. Talk to us about how we can support your security objectives.

Three Disciplines. One Security Practice.

Security architecture is the foundation. Without a coherent architecture spanning identity, data, application, network, and cloud controls, security becomes fragmented and gaps emerge at the joins. We design security into your enterprise architecture from the outset, not as an afterthought.

Identity is the new perimeter. As organisations move to cloud and hybrid environments, who has access to what - and under what conditions - becomes the critical control. We design and implement identity programmes covering IAM, privileged access management, and zero trust principles.

Offensive security tests the reality. Architecture and identity controls are only as good as the assurance behind them. Our offensive security team conducts penetration testing, red team exercises, and vulnerability assessments to find the gaps before an adversary does.

Together, these three disciplines give organisations a complete security picture: a well-designed foundation, a robust identity posture, and independent assurance that controls are working as intended.

Security Architecture

Effective security requires architecture, not just controls. Our security architects work at enterprise, solution, and technical levels - covering the full stack from network segmentation and cloud security posture through to application security and data protection.

We begin with an assessment of your current security architecture - evaluating your estate, identifying gaps, and understanding where controls are missing or misaligned. From there, we develop a target architecture and roadmap aligned to the frameworks and standards relevant to your sector.

For organisations implementing cloud or hybrid environments, we design zero trust architectures that eliminate implicit trust and enforce verification at every layer. This covers micro-segmentation, least-privilege access, continuous monitoring, and cloud security posture management across AWS, Azure, and multi-cloud environments.

We also provide security governance and risk support - helping organisations build frameworks aligned to NIST CSF, ISO 27001, NCSC guidelines, and sector-specific regulations. Whether preparing for certification or managing ongoing risk, we provide the architecture and guidance to make compliance meaningful rather than a checkbox exercise.

Our security architecture capability is available on a project basis, as an embedded resource, or through our Security as a Service subscription model.

Identity and Offensive Security

Identity. We design and implement identity and access management programmes that ensure the right people have the right access under the right conditions. Our capability covers IAM strategy and design, privileged access management, multi-factor authentication, single sign-on, and identity governance. We work across on-premise, cloud, and hybrid environments - helping organisations modernise legacy identity infrastructure and build a robust foundation aligned to zero trust principles. Offensive Security. Our offensive security capability provides independent assurance that your controls are working. We conduct penetration testing across infrastructure, applications, and cloud environments, red team exercises that simulate real-world adversary techniques, vulnerability assessments, and social engineering engagements. All findings are delivered with clear, prioritised remediation guidance - not just a list of CVEs. Both disciplines are available as standalone engagements or as part of a broader security programme. For organisations that need ongoing capability without permanent headcount, our Security as a Service model provides flexible access across all three disciplines.

FAQs

Find answers to common questions about our Security services.

Security architecture is the practice of designing and structuring security controls, policies, and technologies across your enterprise to protect against cyber threats. Every organisation needs a coherent security architecture to ensure protection is embedded consistently across applications, infrastructure, data, and cloud environments rather than applied in a piecemeal fashion. A well-designed security architecture reduces risk, supports regulatory compliance, and enables your business to innovate securely.

Our consultants have deep expertise across all major security frameworks including NIST Cybersecurity Framework, ISO 27001, Cyber Essentials and Cyber Essentials Plus, NCSC guidelines, PCI DSS, and GDPR. We help organisations select the most appropriate frameworks for their sector and risk profile, and provide hands-on support through assessment, implementation, and certification processes.

Zero Trust is a security model built on the principle of never trust, always verify. Rather than relying on traditional perimeter-based security, Zero Trust enforces verification at every layer through micro-segmentation, least-privilege access, and continuous monitoring. This approach is particularly effective for organisations with cloud, hybrid, or remote working environments, as it significantly reduces the attack surface and limits the impact of any potential breach.

Yes. Our security consultants deliver expert penetration testing and vulnerability assessment services covering infrastructure, applications, and social engineering vectors. We identify weaknesses before adversaries can exploit them, providing detailed findings and prioritised remediation recommendations. Our testing methodologies align with industry standards such as OWASP and PTES to ensure comprehensive coverage.

Getting started is simple. Book a free consultation through our contact page and one of our security consultants will discuss your current security posture, challenges, and objectives. From there, we develop a tailored approach, whether that is a security architecture review, a compliance readiness assessment, penetration testing, or a comprehensive cyber strategy engagement. We work flexibly to match your needs and timescales.
