tailored Cybersecurity for companies of all sizes
Defend What
Matters Most
Battle-tested security operations — Penetration Testing, AI Security, OSINT, Breakout Tests, Red Teaming, Blue Teaming, and Threat Intelligence. We simulate real-world adversaries so your defenses hold when it counts.
What We Do
Our Capabilities
Comprehensive security operations built for organizations that cannot afford to be wrong.
Vulnerability Management
Continuous identification, prioritization, and remediation of vulnerabilities across your entire attack surface.
Penetration Testing: Infrastructure
Manual testing of internal and external network infrastructure — servers, firewalls, VPNs, and Active Directory.
Penetration Testing: Web Applications
In-depth manual testing of web apps and APIs — uncovering logic flaws and access control weaknesses scanners miss.
AI Security
Assess and harden AI/ML deployments against adversarial manipulation, data poisoning, and model theft.
OSINT
Map your digital footprint from an adversary's perspective — exposing leaked credentials and attack paths.
Red Teaming
Full-scope adversarial simulations built on your actual threat profile. We think like your adversaries.
Blue Teaming
Detection engineering, incident response readiness, and continuous defensive improvement for your SOC.
GRC
Governance, Risk, and Compliance frameworks that align your security programme to regulatory obligations and board requirements.
Cyber Essentials
End-to-end preparation and certification support for Cyber Essentials and Cyber Essentials Plus — the UK government-backed baseline security scheme.
Security Architecture
A holistic overview of all components across the whole environment to map the framework readiness and overall maturity of the business.
Build Review
A review of golden images for servers or workstations, to assess overall security of the endpoints.
Configuration Review
Systematic review of network devices, such as firewall, router, switch or IDS/IPS system against most common misconfigurations.
Breakout Test: Kiosk / Citrix
Specialist testing of locked-down kiosk and Citrix environments — identifying escape paths to the underlying system.
Cloud Review
Security assessment of Azure, AWS, and GCP — IAM, network controls, data protection, and compliance posture against CIS benchmark.
Penetration Testing: Wireless
Manual testing of wireless infrastructure — rogue APs, weak encryption, authentication bypasses, and client-side vectors.
Social Engineering: Phishing Campaign
Realistic phishing simulations that measure susceptibility and build organizational resilience to email-based attacks.
vCISO / CISO as a Service
Fractional or retained senior security leadership — strategy, governance, board reporting, and programme oversight.
DevSecOps
Embed automated security testing and policy-as-code into your CI/CD pipelines so vulnerabilities are caught at build time.
By the Numbers
Methodology-Driven. Outcome-Focused.
Every engagement at Holistic Security follows a rigorous, repeatable methodology built on industry frameworks — MITRE ATT&CK, PTES, OWASP, and TIBER-EU. We don't run generic scans. We build custom attack scenarios based on your threat profile, industry, and adversary landscape.
Our deliverables go beyond vulnerability lists. You receive executive-level risk summaries, technical remediation guidance, and a measurable security posture baseline — so you can demonstrate progress to your board, regulators, and clients.
