Security
Security is the foundation everything else sits on. Cloudsa's cybersecurity practice designs controls and hardens infrastructure. We build governance frameworks that hold up under scrutiny.
Overview
The threat landscape has changed shape. Ransomware is now a commodity service. Supply-chain compromise has become a primary attack vector. Generative AI has dropped the cost of credible phishing and reconnaissance to near zero. Meanwhile the perimeter security teams spent two decades defending has dissolved. Workforces are remote, workloads live across multiple clouds, and critical data flows through dozens of SaaS vendors you don't control. The old castle-and-moat model is finished. There's no moat left to defend.
Regulatory pressure has risen to match. Boards now ask direct questions about cyber risk. Frameworks like ISO 27001, SOC 2, PCI-DSS, and NIST CSF are now table stakes for winning contracts. Customers and partners increasingly make security posture a condition of doing business. In regulated sectors (financial services, healthcare, public sector, transport), a single material breach can mean regulatory sanction, contract loss, and a reputational hit that outlasts any technical fix.
Zero-trust is the baseline now. Every request authenticated, every identity verified, every privilege minimised, every action logged. Cloudsa's cybersecurity practice is built around this. We begin every engagement, cloud, DevOps, or software, with a security review, because security designed in is an order of magnitude cheaper than security bolted on. We bring both offensive and defensive capability: penetration testers who find the gaps, and architects who close them properly. A focused audit or a multi-year managed-security partnership, the work is the same. We build posture that holds up when tested. By an auditor, or by an adversary.
Capabilities
Eight core capabilities spanning offence and defence. A single security audit, or fully managed SLA-backed security operations.
Threat modelling, attack surface analysis, and architecture review against NIST CSF, CIS Controls, and the Microsoft Cloud Security Benchmark. You get a prioritised remediation roadmap you can act on.
Breadth across the whole organisation: identity, access management, data protection, network segmentation, vendor risk, and incident-response readiness. We find what point-in-time pentests miss.
Infrastructure, web application, and API penetration testing aligned to the OWASP Top 10 and OWASP ASVS, with clear exploit narratives and remediation guidance your engineers can act on.
Identity-centric security with Entra ID conditional access, mTLS, Keycloak, Cloudflare Access, micro-segmentation, and least-privilege enforcement. Sequenced pragmatically, not all at once.
Implementation of Microsoft Cloud Adoption Framework security controls and the Microsoft Cloud Security Benchmark across Azure tenants, with policy-as-code guardrails and continuous compliance.
IR playbooks, tabletop exercises, detection engineering, and SLA-backed 24/7 monitoring with Microsoft Sentinel and Defender XDR. We help you prepare for the bad day before it arrives.
Gap analysis and programme delivery for ISO 27001, SOC 2 Type II, PCI-DSS, and GDPR. Control implementation, evidence gathering, policy authoring, and internal audit through to certification.
Securing AI deployments end-to-end: private endpoints and customer-managed keys, prompt-injection defences and output filtering, plus governance, data classification, and full audit logging.
Frameworks
We map your controls to the standards your auditors, regulators, and customers actually recognise.
Microsoft Cloud Adoption Framework security baseline and governance.
Microsoft Cloud Security Benchmark control mapping and enforcement.
Identify, Protect, Detect, Respond, Recover. The backbone of our assessments.
Information security management system readiness and certification support.
Cardholder data environment scoping, segmentation, and control validation.
Application security testing against the most critical web risks and ASVS.
Industries
Security matters most in regulated, infrastructure-critical sectors. That's where our experience runs deepest.
Zero-trust platforms and fleet-scale identity for transport operators handling thousands of vehicles and millions of daily transactions. Reliability isn't optional here.
Fleet-scale identity & SSO
Security architecture and audit for banks, fintechs, and payment processors. Audit-ready by design. Strong identity governance and segregated environments.
PCI-DSS & ISO 27001 ready
HIPAA-aware platforms and patient data protection for hospitals and digital health providers. Secure infrastructure across multiple sites. Compliance is where we start.
Patient data sovereignty
Citizen-facing platforms and internal systems for government and parastatals. We design for transparency and resilience. These systems need to run for years, so we build for that.
Sovereign deployment models
OT/IT convergence and edge platforms for energy providers and industrial operators. Secure remote operations across plant and grid. We connect the engineering side to IT.
OT/IT secure convergence
Multi-tenant security, secure SDLC, and platform hardening for software companies. We help you ship faster and keep production solid.
Secure platform engineering
Methodology
We map your attack surface, assets, data flows, and existing controls against a recognised framework: NIST CSF, ISO 27001, or MCSB. You get a prioritised risk register and a written assessment everyone aligns on before remediation begins.
We design the target security model: identity and access, network segmentation, data protection, detection coverage, and governance. Every recommendation is risk-ranked and costed, so you invest where it matters most, not where a checklist says to.
Iterative remediation in two-week cycles. Zero-trust enforcement, CIS-hardened baselines, policy-as-code, and detection engineering. Implemented by senior engineers and validated by testing, not just documented.
Handover includes runbooks, IR playbooks, and team enablement. Then optional SLA-backed managed security: 24/7 monitoring with Sentinel and Defender XDR, threat hunting, and continuous control validation as your estate evolves.

FAQ
Zero-trust is a security model that assumes no implicit trust. Every request is authenticated, authorised, and inspected. For modern distributed organisations (cloud, remote work, SaaS, mobile), perimeter security no longer holds. Yes, you need it. The real question is scope and pace, and we'll help you sequence it pragmatically.
Yes. They're different things. A pentest finds exploitable vulnerabilities. A security audit assesses your overall posture: identity, access management, data protection, network segmentation, incident response readiness, vendor risk, compliance. A pentest is depth on a narrow surface. An audit is breadth across the whole organisation.
Our retained managed-security engagements include 24/7 monitoring with defined SLAs (15-minute acknowledgement on Sev-1 incidents, 1-hour on Sev-2). We use Microsoft Sentinel, Defender XDR, and SIEM integrations as standard. For non-retained clients, we offer best-effort incident response within business hours.
We help you become compliance-ready: gap analysis, control implementation, evidence gathering, policy authoring, internal audit. The formal certification itself is performed by an accredited certification body (we're not auditors). We've taken multiple clients through this process successfully.
Three layers. (1) Infrastructure: private endpoints, customer-managed keys, regional isolation, no data egress to model providers without explicit consent. (2) Application: prompt injection defences, output filtering, jailbreak detection. (3) Governance: data classification before LLM exposure, audit logging of all queries, human-in-the-loop where stakes are high. We're building this into our AI engagements as standard.
