Infrastructure Security
Infrastructure-layer security across networks, servers, endpoints, and devices, including network vulnerability assessment and security configuration review benchmarked against CIS, vendor baselines, and your security policy.
Most enterprises still run on infrastructure built over many years, a mix of on-prem, cloud-hosted, virtualised, and edge environments stitched together by network controls and a security configuration that has rarely been reviewed end-to-end. Infrastructure security focuses there: identifying exploitable weaknesses and posture drift before attackers do.
Our infrastructure security service covers two complementary work types. Network vulnerability assessment provides broad, automated coverage with consultant triage, useful for ongoing posture monitoring and audit evidence. Security configuration review is deeper, comparing the actual configuration of devices, servers, and platforms against established hardening baselines.
Both engagement types map findings to CIS Benchmarks, vendor guidance (Microsoft, Cisco, Red Hat, VMware), and the technical control sets in ISO 27001:2022, PCI DSS, and regional regulator frameworks.
What's at stake.
Posture drift is invisible without testing
Configurations change with every patch, role rotation, and emergency fix. Without periodic testing, hardening achieved 12 months ago may no longer reflect production reality.
Vulnerability scanning alone misses context
A scanner flags a CVE. Whether that CVE is exploitable in your environment depends on configuration, network position, and what else an attacker can reach from there. Consultant triage closes that gap.
Auditors increasingly ask for benchmark-aligned evidence
CIS-aligned configuration evidence is becoming the de-facto standard auditors and customers expect, particularly in regulated sectors.
What we test.
Network vulnerability assessment
Broad-coverage scanning of network-accessible assets, with consultant triage to separate signal from noise.
- Network devices, servers, endpoints
- External and internal coverage
- Configuration errors and missing patches
- Risk-prioritised vulnerability identification
- Compliance-aligned reporting
CIS Benchmarks
Deep configuration analysis comparing live posture against established CIS hardening baselines.
- Operating systems (Windows, Linux, macOS)
- Network devices (firewalls, switches, routers)
- Hypervisors and virtualisation platforms
- Databases (SQL Server, Oracle, PostgreSQL, MySQL)
- Endpoint and EDR configuration
The flaws engagements like this consistently surface.
Drawn from common categories our consultants surface across engagements of this type. Severity and prevalence vary by environment and maturity.
Missing patches on exposed services
Internet-facing services running versions with known RCE, internal services months behind on critical updates, legacy systems with no remediation path.
Weak protocols still enabled
SSLv3 / TLS 1.0 on external services, SMBv1 on internal segments, deprecated cipher suites accepted on management interfaces.
Configuration drift from baseline
Hardening reverted after troubleshooting, default credentials never rotated, audit settings disabled "temporarily", local admin accounts proliferating.
Network segmentation gaps
Flat networks with no segmentation between user and server subnets, overly broad firewall rules, missing egress controls.
Logging and monitoring blind spots
Critical infrastructure not forwarding to SIEM, log retention shorter than incident response requires, alerts firing without anyone subscribed.
Forgotten exposures
Decommissioned-but-still-running services, test environments reachable from production, legacy VPN endpoints with weak authentication.
A structured, thorough review of every infrastructure asset.
Each engagement walks methodically through networks, servers, endpoints, and devices, benchmarking actual configuration against CIS, vendor baselines, and the technical controls your regulators and auditors expect to see.
Scoping
Define assets, environments, Rules of Engagement, and acceptance criteria with the technical and security stakeholders.
Execution
Manual and tool-assisted testing by CREST-accredited consultants, with evidence captured at each step.
Validation
Every finding is reproduced, risk-rated under CVSS, and confirmed by a second consultant before reporting.
Reporting
Cryptographically signed reports with test-case traceability, severity ratings, reproduction steps, and remediation guidance.
Debrief & Retest
Stakeholder walk-through of findings, prioritisation support, and a retest cycle on remediated issues.
Mapped to recognised baselines.
Reports built for audit, engineering, and executive review.
Every engagement produces verifiable, traceable, regulator-ready artefacts, generated by Velocity and signed cryptographically.

Common buyer questions.
How is this different from running our own vulnerability scanner? +
Scanning is one input. The value of an engagement is in consultant triage: validating findings, filtering false positives, contextualising exploitability against your environment, and translating output into prioritised remediation a board can read.
Will this affect production systems? +
Vulnerability scanning is designed to be non-disruptive at normal intensity. We agree scanning windows and exclusion lists with you before the engagement, and avoid known-fragile assets unless they are explicitly in scope.
How often should infrastructure be tested? +
Most regulated organisations run an external scan quarterly, an internal scan and configuration review annually, and ad-hoc reviews after significant changes. Engagements can be configured as one-off or as a continuous programme.
Can you cover both on-prem and cloud-hosted infrastructure? +
Yes. Hybrid environments are the norm. Cloud-specific identity and configuration testing is handled under our Cloud Security service line, and the two are usually combined in a single engagement.
