The evolving education attack surface set out how fast estates have grown across UK higher and further education. This article gets practical. It takes the five security gaps that define the sector and shows how attack surface management closes each one in practice. They are decentralised IT, a legacy-plus-cloud mix, third-party research risk, limited resources, and multi-framework compliance. If you already suspect your estate is bigger than your asset register, this is how you get it back under view.
UK universities and colleges balance openness for academic collaboration with protecting sensitive research data and student information. Most institutions are working against:
Here’s how a comprehensive attack surface management (ASM) solution addresses these pain points in practice.
When IT is managed at the department level, keeping an accurate inventory across the whole estate manually is nearly impossible. Shadow IT is a serious concern for institutions of any size, you can’t protect what you don’t know exists. Hexiosec ASM’s continuous asset discovery reduces that risk by constantly scanning the institution’s online infrastructure and recording new assets as they appear.
By identifying the true scale of the attack surface, previously unknown assets can be found and brought under proper security governance, particularly valuable where no departmental server or research project portal should be able to sit outside that view for long.
The NCSC advocates for risk-based security, prioritising resources and action based on the likelihood and impact of a given threat, but many institutions struggle to put that guidance into practice day to day. [1]
Hexiosec ASM includes built-in vulnerability discovery that scores issues by severity and flags Known Exploited Vulnerabilities (KEVs), so resource-constrained teams can prioritise remediating what poses the greatest real threat first, rather than working through an undifferentiated list.
UK higher and further education institutions must adhere to standards including Cyber Essentials, Cyber Essentials Plus, and sector-specific frameworks.
Hexiosec ASM surfaces where misconfigurations arise, what’s causing them, and how they affect other systems, providing the visibility needed to maintain compliant configurations and avoid common pitfalls like insecure defaults or unnecessary open ports.
UK universities regularly collaborate with international research partners, commercial organisations and vendors, each a potential security liability.
Hexiosec ASM’s non-intrusive scanning is well suited to assessing supply chain and third-party connections without disrupting those relationships, surfacing weak points where infrastructure interfaces with external parties.
With research data carrying real intellectual and financial value, and supply chain attacks on the rise, protecting these collaborative environments matters more than ever.
As UK higher education institutions increasingly migrate to cloud services like Microsoft 365, AWS, and specialised research platforms, maintaining visibility across hybrid environments becomes challenging.
Hexiosec ASM continuously monitors your public-facing assets with daily scan refreshes, ensuring you’re promptly alerted to new vulnerabilities as they emerge across both on-premises and cloud environments. This continuous monitoring provides peace of mind as your institution’s digital footprint evolves and gives you the insight to make changes quickly when new threats or vulnerabilities appear.
A practical workflow for higher and further education security teams:
Jisc’s 2026 conference theme is secure foundations, and you can’t build secure, scalable infrastructure on an estate you can’t see. Discovery first, then daily scans to keep the picture current, is what makes the other four steps possible.
Hexiosec ASM is available to Jisc members through the Chest platform , with exclusive member discounts and terms, a well-established buying channel rather than an unfamiliar new vendor asking institutions to step outside normal procurement.[2]
UK higher and further education institutions face distinct cyber security challenges, from decentralised IT governance to complex research partnerships. A comprehensive attack surface management solution like Hexiosec ASM addresses these sector-specific needs directly: continuous discovery, risk-based prioritisation, and remediation workflows that actually get used.
How does attack surface management help with decentralised IT in higher education? Continuous asset discovery scans an institution’s online infrastructure on an ongoing basis, rather than relying on a central register that department-run systems and research-group infrastructure routinely fall outside of. New assets are recorded as they appear, so a server or portal set up outside central IT doesn’t stay invisible for long.
What’s the difference between a periodic vulnerability scan and continuous attack surface management? A periodic scan gives a snapshot that starts going out of date the moment it’s finished. Continuous ASM refreshes daily, so new vulnerabilities and newly exposed assets are flagged as they appear rather than at the next scheduled review.
Is Hexiosec ASM available through Jisc? Yes. Hexiosec ASM is available to Jisc members through the Chest platform, with exclusive member discounts and terms, a well-established procurement route rather than a new vendor relationship.
What does implementing attack surface management actually involve? A six-step workflow: discover the unknown estate from a domain or IP address, explore the data in detail, understand risk using severity and KEV data, prioritise remediation on a built-in Kanban board, monitor continuously with daily refreshes, and share concise PDF reports with stakeholders.
See it in person: we’ll be running live Hexiosec ASM scans at the Jisc Security Conference, Manchester Central, 24-25 November. Book a meeting, start a free scan, or watch our existing ASM webinar with Jisc first.

Next: The national picture of risk, and once you know what’s exposed, encrypted transfer and data regulations and the compliance roadmap cover the other half of the picture: moving sensitive data off that estate securely.
