Attackers rarely break in through the front door. They move laterally through misconfigured services, unpatched endpoints, overprivileged accounts, and log gaps that no one is watching. By the time an alert fires, the dwell time has often stretched into weeks.

Most organisations have some security tooling in place. What they lack is operational discipline: hardened baselines enforced consistently, logs aggregated and actioned, patch cycles that close real vulnerabilities before they are exploited. That gap between tooling and operations is where incidents begin.

Gradion builds the defensive layer that holds. We embed directly into infrastructure and security teams, running structured hardening programmes and standing up monitoring capabilities that persist after the engagement ends. Not policies. Working systems.

Managed vulnerability scanning

The Blue Team runs continuous vulnerability scanning on a subscription basis - giving organisations a live picture of their exposure rather than a point-in-time report that is outdated within weeks. Ten or more concurrent scanning subscriptions run in parallel across our client base. Coverage is ongoing, findings are triaged by severity and business impact, and the team is available to act on what it finds, not just report it.

This is the foundation. Everything else builds on knowing what is actually exposed.

Cloud security assessment and hardening

Assessment against CIS, NIST, PCI DSS, and SOC 2 benchmarks. Three to five days for the assessment; one to two weeks for hardening. Deliverables: Security Posture Report, Hardening Roadmap, and Monitoring Setup. We do not produce a report and leave the remediation to someone else - the hardening phase is part of the engagement.

System hardening

We baseline every environment against established benchmarks - CIS Controls, BSI IT-Grundschutz, or client-specific standards - and close the gaps that audits miss. OS hardening, service reduction, secure boot configurations, removal of default credentials and unnecessary exposure. For A high-volume B2B marketplace, we delivered security hardening including AWS WAF deployment as part of a broader infrastructure stabilisation programme. The platform handles significant transaction volumes; tightening the perimeter was non-negotiable before scaling further.

Log monitoring and SIEM implementation

Logs are only useful if someone is watching them. We design log aggregation pipelines, define alert logic tuned to your environment, and implement SIEM configurations - whether on platforms you already hold licences for or as a net-new deployment. Alert fatigue kills monitoring programmes. We focus on signal-to-noise ratio from day one: fewer alerts, higher fidelity, faster triage. Deployments cover Splunk, Elastic Security, and Microsoft Sentinel.

Threat detection runbooks

Detection without response is noise. We build threat detection runbooks mapped to your actual environment - which services exist, which users are privileged, which data is sensitive. Runbooks define detection logic, triage steps, escalation paths, and containment actions. Teams inherit a live playbook, not a slide deck.

Identity and access management hardening

Privilege sprawl is the defensive perimeter’s largest gap. We audit IAM configurations across cloud and on-premises systems, enforce least-privilege access, implement MFA where it is missing, and govern service account proliferation. Identity is treated as infrastructure - versioned, reviewed, and audited.

Patch management

Unpatched systems are the most common attack vector, yet patch management remains informal in most mid-market organisations. We design and operationalise repeatable patch cycles: asset inventory, criticality triage, staged rollout, and rollback procedures. Patching is treated as an engineering process, not an afterthought.

Compliance alignment

Gradion holds ISO 27001 certified security processes. Where clients are preparing for ISO 27001 or NIS2 audits, our hardening programmes are scoped to close the specific gaps those frameworks test. We have delivered Cybersecurity & Infrastructure Safety Checks covering both IT and OT scopes - cross-domain threat visibility, network segmentation review, and executive-level risk scorecards - in approximately three-week engagements.

Technology

AWS (Security Hub, GuardDuty, WAF, CloudTrail), Azure (Defender for Cloud, Sentinel, Entra ID), on-premises Linux/Windows, and hybrid configurations. Tool choices follow what the client already operates - we do not create new vendor dependencies without a clear case.

How we work

Engagements scoped in days, teams mobilised in weeks, hardening work shipped in production. We do not hand over a report and exit. The systems we harden stay hardened. The monitoring we build gets maintained. The runbooks we write get tested.
