Safeguard your computer security with ongoing support from our dedicated computer security incident response team.

The cyber threat landscape is always evolving. Threat actors are continuing to target educational institutions, causing extensive damage and lengthy, expensive disruption. Jisc’s CSIRT team provides your first line of defence against cyber threats. Our world class incident response service works to create a secure environment for your organisation by monitoring and resolving any security incidents that occur on your network.

We work closely with other cyber security organisations and members of our cyber community to detect, report and investigate incidents that pose a threat to the security of our members' information systems. We also investigate other forms of network abuse such as spam and copyright infringement.

“When faced with a complex and time-critical incident, Jisc provided the highest level of professionalism, responsiveness and technical expertise. The information was shared and presented in such a way that even non-ICT experts were able to engage with the work being done."
Vice-principal, Northampton College

Information security threats are not limited to particular networks or national boundaries, so we assist national and international law enforcement agencies in their investigations, connecting them to our trusted contacts within the community. We work with other computer security incident response teams across the UK, Europe and the rest of the world to manage and resolve incidents. Through our work, we have built strong relationships with other security researchers and sources of security reports to ensure we provide you with a fast and effective response.

Groups and organisations we work with:

  • The National Cyber Security Centre
    Jisc works closely with the NCSC, which provides us with actionable threat intelligence that we use to continuously improve the ability of our security services to address the dynamic threat landscape.
  • GÉANT Security Services
    GÉANT Security Services is a task force that promotes collaboration between CSIRTs at the European level, and liaises with similar groups in other regions.
    FIRST brings together a variety of computer security incident response teams from government, commercial, and educational organisations.
  • Trusted Introducer
    Trusted Introducer is the backbone of the security and incident response team community in Europe.
