Education Technology: How Telecommunications Supports Schools and Universities

Why is connectivity now a safeguarding issue in education?

Connectivity stopped being a convenience the moment teaching, assessment and safeguarding moved online. When the network drops during an online exam or a remote lesson, learning stops — and so does the filtering that keeps children safe. That makes the line into the building a safeguarding control, not just an IT line item.

A secondary school in 2025 routinely runs all of the following at once:

• Simultaneous 4K video for remote and hybrid lessons
• Online examination platforms with strict bandwidth and latency rules
• Staff on Microsoft 365 security and cloud-based MIS systems
• Pupil devices in 1:1 or BYOD programmes
• Visitor and guest WiFi, kept off the staff network

All of this has to run while the school meets the filtering and monitoring duties set out in Keeping Children Safe in Education (KCSIE). Consumer or entry-level broadband — which many smaller schools still rely on — is structurally inadequate. Contention, latency and the absence of an SLA turn a busy exam morning into an outage. The right answer usually starts with proper business leased line connectivity and a managed cybersecurity wrapper around it.

What connectivity options should schools and colleges choose?

The right connection depends on size, site count and how exam-critical the network is. Secondary schools, sixth-forms, FE colleges and universities should treat a dedicated leased line as the baseline. Smaller primaries can often start with full fibre. Multi-site trusts and universities need SD-WAN to manage traffic across campuses.

Leased lines

A leased line is uncontended: the full bandwidth is reserved for the institution, with guaranteed symmetric upload and download and a real SLA. Symmetric speeds run from 100 Mbps to 100 Gbps depending on the site. Leased line connectivity for schools starts from £69 per month depending on speed and location. Many institutions buy through regional broadband consortia or JISC (for HE/FE) to aggregate purchasing power.

FTTP full fibre

Where a leased line is cost-prohibitive, Full Fibre to the Premises (FTTP) is a big step up from ADSL or VDSL. Speeds up to 1 Gbps are widely available, and the symmetric profile of full fibre helps upload-heavy tasks like video conferencing. FTTP does not carry leased-line SLAs, so use it for lower-demand sites or as a secondary, resilient connection.

SD-WAN for multi-site institutions

Multi-academy trusts and multi-campus universities benefit from SD-WAN, which routes traffic intelligently across multiple links, prioritises real-time applications like video over background sync, and gives central visibility of every site from one management plane.

Why is the education sector such a big cyber target?

Education is disproportionately targeted because it holds sensitive personal data on children and staff, often runs lean IT security teams, and depends on continuous system availability. Education-sector cyber surveys have found as many as 78% of further education colleges hit by a significant cyber incident (UK sector data, 2023). Ransomware is the headline threat, and it hits hard.

Ransomware attacks on schools, colleges and universities have caused real damage — lost examination data, student records and financial systems. An attack on a multi-academy trust can take several schools offline at once. The National Cyber Security Centre's education guidance recommends a consistent core of controls: offline backups, network segmentation, multi-factor authentication and disciplined patching.

AMVIA's view is blunt: schools do not need more tools, they need the basics done properly and watched. MFA on every staff account, segmented pupil and staff networks, and tested offline backups will stop the overwhelming majority of incidents before they spread. When something does get through, fast incident response and recovery is what limits the damage — and the sector-specific risk is covered on our education cybersecurity page.

How should schools meet KCSIE filtering and monitoring duties?

Schools in England must have appropriate filtering and monitoring under KCSIE: block harmful and illegal content, monitor for indicators of radicalisation or vulnerability, and make sure monitoring is actively reviewed rather than left to create a false sense of security. The DfE's Filtering and Monitoring Standards, updated in 2023, give a concrete checklist.

The standards make three things explicit:

• Filtering must block the content categories the DfE specifies, for all users and devices
• Monitoring must be active and reviewed — a switched-on system nobody checks does not meet the duty
• Governance is named: a senior leader and a governor must own filtering and monitoring

Self-assess against the DfE filtering and monitoring standards at least annually, and keep the evidence. Where pupil data is involved, the Information Commissioner's Office sets the data-protection obligations that sit alongside KCSIE.

How is unified communications changing education?

Telephony and collaboration are converging on Microsoft Teams and VoIP, driven partly by the PSTN switch-off. Legacy analogue lines are being retired, and digital telephony cuts cost while adding flexibility — calls between sites over the data network, Teams integration for staff, and simple extension management as staffing changes.

Microsoft Teams in schools

Teams is now standard for virtual lessons, staff communication, parent engagement and document collaboration, and qualifying schools can access Microsoft 365 Education licensing at heavily reduced or no cost. The risk is governance: many schools deployed Teams fast and never added the controls that stop inappropriate sharing of pupil data or unmonitored safeguarding channels. That governance layer is exactly what proper Microsoft 365 management exists to provide.

VoIP and the PSTN switch-off

The PSTN switch-off forces migration off analogue lines. Openreach is retiring the legacy network, with the all-IP migration now running into 2027. Schools should audit every analogue line — phones, fax, fire-alarm diallers, door entry — and migrate to business VoIP and Teams Calling before their exchange is affected.

What should education IT leaders do now?

Start with the controls that move the needle most: connectivity that won't fail during exams, MFA everywhere, and tested backups. Everything else follows. Here is the practical checklist AMVIA gives school and trust IT leaders.

• Audit current connectivity against real usage — bandwidth monitoring shows peak utilisation and where the constraints actually are
• If you are on ADSL or ageing VDSL, model a leased line against the cost of connectivity failures during exams and remote sessions
• Apply MFA to every staff Microsoft 365 account — the single highest-impact control against account compromise
• Separate pupil device networks from staff networks using VLANs
• Make sure filtering meets the DfE standards and that monitoring is genuinely reviewed
• Test offline backup restoration — too many schools discover their backups were inadequate only during an incident
• Plan for the PSTN switch-off now if you have not already migrated telephony
