Protect your servers, data and reputation

Your ERP and business applications hold your most valuable data. We harden servers, secure applications, monitor threats and make sure you can recover quickly if the worst happens.

Security services

Defence in depth

Server hardening

Secure Linux and Windows server configuration: minimal services, patched OS, locked-down SSH and RDP, firewall rules.

Security audits & assessments

Configuration reviews, vulnerability scans and a prioritised remediation report.

Application security

OWASP Top 10 reviews, secure coding, dependency scanning and secrets management.

Network & perimeter security

Firewalls, VPN, WAF, DDoS protection, network segmentation and zero-trust access.

Identity & access

Two-factor authentication, single sign-on, least privilege and regular access reviews.

Monitoring & threat detection

Centralised logging, intrusion detection, uptime monitoring and real-time alerts.

Backup & disaster recovery

Encrypted, off-site backups with tested restore procedures and recovery targets.

Incident response

Rapid containment, investigation and recovery if a security incident occurs.

Compliance support

Technical controls that support GDPR, ISO 27001 and similar frameworks.

Hardening checklist

What we lock down on every server

A sample of the controls we apply as standard to every server and application we manage.

Operating system

  • Automated security patching
  • Unused services disabled
  • SSH keys only, no root login
  • Fail2ban / brute-force protection

Network

  • Firewall default-deny
  • Admin ports behind VPN or IP allow-list
  • TLS 1.2+ with strong ciphers
  • WAF and rate limiting

Data

  • Encryption at rest and in transit
  • Database not exposed publicly
  • Encrypted off-site backups
  • Restore drills

Visibility

  • Centralised logs
  • Intrusion detection
  • File-integrity monitoring
  • 24/7 uptime alerts
Process

Inventory servers and apps, scan for vulnerabilities and review configurations.

Report

Clear findings ranked by risk, with business impact and fixes.

Remediate

We fix the issues, harden systems and document every change.

Monitor

Continuous monitoring, patching and periodic re-assessment.

FAQ

Security questions

Can you secure servers you did not set up?

Yes. We start with an audit of your existing servers and applications, then fix and harden them.

Do you offer ongoing security monitoring?

Yes, as part of our managed infrastructure and support plans.

How often should we audit our servers?

At least annually, and after major changes. Critical systems benefit from continuous scanning.
