About Quadrant Information Security

Quadrant Information Security is a cybersecurity company offering consulting and managed security services. It describes itself as a group of security professionals rather than auditors. Its site now states that Quadrant has joined Harbor IT, a national provider of managed IT and cybersecurity.

What Quadrant Information Security offers

  • Managed SIEM — monitoring, analysis and reporting on client data by its own security operations centre.
  • Sagan technology — its own proprietary technology used within its security service.
  • Enterprise security consulting — advice from security specialists on keeping an environment secure.
  • Threat detection and response — 24/7 detection, response and threat hunting.
  • Offensive security — continuous testing and validation of defences.

Who it works with

Existing clients keep the same dedicated security team. Following the move into Harbor IT, they can also draw on its wider expertise in cloud, infrastructure, applications, compliance and managed IT.

Key facts

  • Parent: Harbor IT, a national managed IT and cybersecurity provider
  • Approach: combines people with product, and keeps security operations separate from managed IT delivery
