Managed Security Services

Keep your security working, every day.

Your security tools need more than installation. Apexagen works alongside your team to maintain controls, address vulnerabilities and keep you prepared, with clear ownership and progress you can see.

Let's talk about your security Explore the service areas ↓

Where we can help

Five areas. One coordinated security service.

Bring in support where your team needs it most, or combine several areas into an ongoing programme. Explore each area to see the activities and deliverables we can agree with you.

Security Platform & Infrastructure Management

Get more from the security tools you already rely on. Keep policies, configurations and platform health aligned with your environment.

Explore the scope
  • Health and coverage checks for agreed firewalls, endpoint protection and security platforms.
  • Firewall rule reviews, policy tuning and configuration baselines to address gaps and unnecessary access.
  • Cloud and Microsoft 365 security configuration reviews, with agreed improvements tracked to completion.
  • Approved upgrades and changes, configuration backups and coordination with technology vendors.

What you receive: A record of platform health, approved changes and outstanding control issues.

Vulnerability & Cyber Hygiene Management

Turn assessment findings into improvements that last. Prioritise the exposures that matter and follow through on remediation.

Explore the scope
  • Scheduled vulnerability assessments across agreed assets and services.
  • Prioritisation using exposure, exploitability and business impact, with remediation owners and target dates.
  • Patch coordination and secure configuration reviews, including exceptions for systems that cannot be changed immediately.
  • Retesting and closure evidence to verify fixes and identify recurring weaknesses.

What you receive: A prioritised remediation register showing progress, exceptions and verified fixes.

Identity, Access & Device Governance

Know what is connected and who can access it. Reduce unmanaged devices, excessive privileges and uncontrolled third-party access.

Explore the scope
  • User and privileged access reviews, including joiner, mover and leaver controls.
  • Device inventory, ownership and posture reviews to identify unknown or non-compliant assets.
  • Network access control policies, device exceptions and remediation workflows.
  • Privileged and vendor access oversight, including approval, session review and access expiry where supported.

What you receive: Access review records, device exceptions and a clear set of actions for policy improvement.

OT Security Management

Strengthen industrial security around the way your operation runs. Build visibility and control without treating production systems like ordinary IT.

Explore the scope
  • OT asset visibility and monitoring-platform health reviews using agreed, operationally appropriate methods.
  • Segmentation and firewall policy reviews at IT/OT boundaries.
  • Vendor remote-access reviews and coordination of approved access controls.
  • Risk-based remediation planning with asset owners, maintenance windows and compensating controls considered.

What you receive: An OT risk and action register with agreed priorities, owners and operational constraints.

Incident & Recovery Readiness

Prepare the people and procedures before an incident puts them to the test. Make escalation and recovery easier to act on.

Explore the scope
  • Incident response procedures, contact lists and escalation routes tailored to your environment.
  • Tabletop exercises to test decisions, communications and coordination.
  • Backup policy reviews and coordination of agreed restoration tests and recovery checks.
  • Coordination with your MDR provider and internal teams on response authority, remediation and lessons learned.

What you receive: Updated response procedures, exercise findings and recovery-test actions.

Built around your team

Start with the support you need

Choose the areas that need consistent attention. We will work with you to shape a practical service around your systems, people and priorities.

Talk with our team

The final scope covers your agreed assets, platforms, service hours and responsibilities. Changes follow your approval process, and OT activities are planned with operational owners.

What you receive

Clear ownership. Visible progress.

Reporting runs across your service, so you can see what has been completed, what remains open and where attention is needed.

A service plan that fits

Agreed systems, activities, responsibilities and review frequency, with a clear route for requests and escalation.

Actions tracked to closure

A shared record of risks, remediation, changes and exceptions, with owners, priorities and supporting evidence.

Reports you can use

Service reviews covering control health, completed work, outstanding risks and the next priorities for your team.

Working together

Managed security and MDR, connected.

Managed Security Services maintains your controls and follows through on improvements. Managed Detection and Response monitors security activity, investigates threats and coordinates response.

Use either service on its own, or combine them so incident findings feed into lasting improvements to your defences.

A few questions you may have

Can you work with our existing security tools?

We start by reviewing the tools and processes you already use. Supported platforms, licensing, access and integration requirements are confirmed during scoping, so the service has clear boundaries.

Is 24×7 monitoring included?

Service hours and support arrangements are agreed for your managed security scope. If you need 24×7 threat monitoring, investigation and response, explore our separate Apexagen MDR offering, which can be combined with this service.

Can we start with one area?

Yes. We can shape the engagement around a defined need, such as vulnerability remediation or access governance, and review additional areas as your priorities develop.

Will you make changes directly to our systems?

We agree which activities Apexagen performs and which remain with your internal team or vendors. System changes follow the agreed permissions, approval process and maintenance windows.
