Cesta delivers practical, outcome-focused cybersecurity services to organisations that need enterprise-grade security know-how — without building a full in-house team to get there.
Whether you need a one-time assessment or an ongoing security partnership, Cesta brings the depth and pragmatism to make it stick.
Strategic security leadership without the full-time cost. We embed as your virtual CISO to build programmes, manage risk, align with the board, and own your security roadmap.
EnquireDesign security in from the start. We review system architecture, model threats against your context, and produce recommendations engineering teams can actually act on.
EnquireNavigate ISO 27001, SOC 2, NIST, GDPR, and more with pragmatic governance structures and risk programmes that satisfy auditors without drowning your team.
EnquireBuild a security-conscious culture through targeted training programmes, realistic phishing simulations, and metrics that show exactly where human risk is improving.
EnquireControlled, real-world attack simulations across your network, applications, and people. Find exploitable weaknesses before adversaries do — with a clear remediation path.
EnquireFull-scope adversary simulation beyond a point-in-time pen test. We emulate real threat actors — including breach and attack simulations — to stress-test your people, processes, and controls together.
EnquireCollaborative red-and-blue sessions that sharpen detection and response. Tabletop exercises expose gaps in your playbooks before a real incident does.
EnquireAdversarial testing purpose-built for LLM and AI systems — prompt injection, jailbreaking, model extraction, and multi-step manipulation. Informed by current AI threat intelligence.
EnquireEvaluate the security posture of your AI and ML systems — covering model theft, training data poisoning, adversarial inputs, insecure APIs, and supply-chain risks. Designed for organisations building or deploying AI in production.
EnquireBuild the policies, risk frameworks, and controls your organisation needs to deploy AI responsibly. Covers AI risk classification, model governance, and alignment with emerging regulations including the EU AI Act.
EnquireEvery engagement begins with a no-obligation scoping call. We'll map your priorities to the right service mix.
Book a callProactively search for threats that have evaded your existing controls. We develop hunt playbooks, tune detection logic, and help your team stop relying solely on alerts to find attackers.
EnquireDesign your detection architecture, implement and tune your SIEM, and build detection content that generates signal — not noise. Platform-agnostic advisory across Sentinel, Splunk, and others.
EnquireEvaluate how well your defensive controls actually detect and respond to attacks. Run alongside red team engagements or as a standalone exercise — with concrete improvements as the output.
EnquireDesign or mature your security operations function — from tooling selection and process design to analyst workflow and escalation paths. Advisory-led, built around your team's actual capacity.
EnquireRapid containment, investigation, and recovery when a breach occurs. We help you limit damage, understand the root cause, and build resilience so it doesn't happen again.
EnquireContinuous identification, risk-based prioritisation, and remediation tracking across your environment — so your team always knows what to fix first and can demonstrate progress.
EnquireSecure software from design to deployment. Threat modelling, code reviews, SAST/DAST assessments, and API security — so vulnerabilities don't ship to production.
EnquireArchitecture reviews, segmentation strategy, firewall policy analysis, and network monitoring recommendations to protect your perimeter and internal traffic.
EnquireHarden servers, endpoints, and on-premise systems against misconfiguration, privilege escalation, and lateral movement — from baseline assessments to continuous hardening.
EnquirePosture assessment, CSPM guidance, misconfiguration remediation, and secure landing zone design for AWS, Azure, and GCP environments.
EnquireZero Trust architecture, privileged access controls, MFA strategy, and identity lifecycle governance that eliminates credential-based risk at scale.
EnquireMost security engagements produce a long list of findings and leave you to figure out the rest. Cesta stays with you from scoping to remediation — so recommendations actually get implemented.
Start a ConversationWe understand your environment, risk appetite, regulatory obligations, and priorities before recommending anything. No templated proposals.
Hands-on testing, review, or advisory work — appropriate to the service. We find real issues, not checkbox outputs.
Findings ranked by actual business risk, not CVSS scores in isolation. Executives and technical teams both get something useful.
We don't disappear after the report. We support your team through remediation, re-testing, and closing the loop on every finding.
For organisations that want a long-term security partner rather than a series of point engagements, we offer retainer-based models across all service areas.
Security services are only as good as the people delivering them and the outcomes they drive.
Our team works at the intersection of AI and security — giving you coverage of both traditional threats and the emerging AI attack surface that most vendors miss.
Every engagement is designed around what changes, not what gets delivered. We measure success by risk reduced, not pages written.
No bait-and-switch. The people scoping your engagement are the people doing the work — experienced practitioners, not junior analysts supervised from a distance.
We scope to what you actually need. No bloated retainers, no unnecessary scope creep — just focused work that moves the needle on your security posture.
Start with a no-obligation conversation. We'll help you identify your highest-priority gaps and the right services to address them.
