Fewer Open Doors Means Fewer Ways In for Attackers
Infrastructure Hardening Services
Default configurations, unnecessary services and unpatched systems give attackers far more room to work with than most businesses realise. We harden your servers, networks and infrastructure against real-world exploitation techniques.

- OSCP, CEH, CRTP & industry-certified testers.
- Real-World Approach
- Manual testing with real-world attack techniques.
- Actionable Reporting
- Detailed findings with clear risk ratings and remediation.
- Confidential & Secure
- Strict NDA, data protection & privacy practices.
// Infrastructure Hardening
Removing the Unnecessary Risk Built into Default Configurations
Most infrastructure is deployed with convenience in mind, not security. Unused services stay enabled, default credentials go unchanged, and patching falls behind. We review your servers, network devices and infrastructure configuration against recognised hardening benchmarks and close the gaps attackers rely on most.
We work with UK businesses across on-premises, cloud and hybrid infrastructure, from a handful of servers to complex, multi-site environments.
- A Measurably Reduced Attack Surface across Servers and Network
- Infrastructure Aligned to CIS Benchmarks
- A Patching and Configuration Baseline Your Team Can Maintain

// Impact
Why Hardening Matters More than Most Businesses Realise
Defaults Are a Documented Target
Default configurations are well known to attackers and trivially searchable.
// How We Harden Your Infrastructure
- Server and operating system configuration review against CIS Benchmarks
- Network device and firewall rule review to remove unnecessary exposure
- Patch management and vulnerability review across your infrastructure estate
- Unnecessary service and protocol removal to shrink your attack surface

// Standards and Frameworks We Work With
// Why Pluto Cyber Security
Hardening That Reflects How Attackers Actually Operate
We base our hardening recommendations on real attack techniques, not just a generic checklist. Every finding is explained in terms of how it could actually be exploited, so your team understands exactly why each fix matters.
Grounded in Real Attacker Technique
Recommendations come from the same team that runs the penetration tests.
On-Premises, Cloud and Hybrid
Consistent coverage wherever your infrastructure actually runs.
Baselines You Keep
You leave with reusable configuration baselines, not just a point-in-time report.
This depends on the size of your environment, but most engagements take between one and three weeks.
