Report Card: Education Is the Most Attacked Network Environment in SonicWall’s Telemetry

The sector running on the fewest security resources is also dealing with the most difficult detention. Class is in session.

Ah, report card day. For some of us, it was a time of pride. You had straight A’s. You knew your parents were going to be proud. Perhaps you were even going to get a personal pan pizza for free for your hard work. For others? A time of peril. Coming up with excuses for why you got a C or D, scrambling to ask the teacher if there’s anything you can do for a better grade. Right now, education's cybersecurity is unfortunately resembling the latter. And it’s not being graded on a curve.

Education’s 2026 cybersecurity report card showed 82,000 IPS hits per device in the first half of the year, the highest per-device attack intensity of any vertical SonicWall tracks. Higher than finance. Higher than healthcare. Higher than any sector with the budget and regulatory pressure to actually do something about it.

That’s the uncomfortable irony at the center of education’s security story. The most targeted network environment in the telemetry is also the one operating on the tightest security budgets, with the most understaffed security teams, defending an architecture that was never designed to be secure in the first place. 

And much like a kid handing in a less-than-stellar report card to mom and dad, education as an industry still has to answer to angry parents when sensitive data becomes compromised.

The Network Was Built to Be Open

University campuses and school districts don’t run open networks because they don’t know better. They run open networks because that’s what the mission requires. Student devices, faculty research systems, residential networks, third-party learning platforms, public-facing portals, all sharing infrastructure by design. Bring your own device isn’t a policy choice in higher education. It’s the fundamental architecture.

That openness creates an attack surface that’s genuinely unlike anything in any other sector. High credential turnover, thousands of external access points, a transient user population, and security teams that are chronically outnumbered by the environment they’re defending. It’s not a configuration problem. It’s a structural one.

Half of All Attacks Are Going After One Thing

Here’s the number that should stop any education IT professional mid-scroll: SIPVicious generated 90 million combined hits in the first half of 2026, occupying both the first and second positions in education’s top ten attack signature list. Those hits represent 50.5% of every IPS event recorded across the entire vertical. No other single attack type dominates any other sector’s threat profile to this degree.

The reason is structural. Educational institutions have broadly adopted SIP-based VoIP systems for campus communications, distance learning, and multi-site coordination, often on infrastructure that predates modern security standards and hasn’t been comprehensively hardened since. SIPVicious is designed precisely for this environment. It finds exposed SIP endpoints, probes for weak authentication, and can move laterally from a phone system into any network it shares infrastructure with. In a university environment, that means student health records, financial aid data, and research IP are all potentially reachable from a compromised VoIP endpoint.

The Cameras, the Databases, and the Five-Year-Old Vulnerability

SIPVicious isn’t the only problem. Hikvision’s command injection vulnerability, disclosed in 2021, is present on 28% of all education networks in this dataset. That’s more than a quarter of institutions running unpatched cameras on networks that also carry student records and faculty research. Log4Shell is still generating 6.7 million hits against learning management and administrative middleware. MongoBleed, targeting MongoDB instances widely used for research data and LMS backends, added 2.5 million more.

The pattern is consistent: education networks are carrying years of unpatched infrastructure, and attackers have learned exactly where to look.

The Ransomware Problem Nobody Is Talking About

Education recorded the lowest absolute ransomware volume of any tracked vertical in H1 2026. That’s not reassuring. It reflects deliberate, targeted intrusion campaigns rather than broad automated attacks. Forty-four organizations detected active ransomware campaigns in the first half of the year alone.

In most sectors, ransomware is an operational disruption. In education, it’s also a federal compliance event. Student records fall under FERPA. Research data is grant-funded, years in the making and often irreplaceable. It doesn’t restore from yesterday’s backup. The stakes of a ransomware incident in education aren’t just downtime. They’re the dissertations that can’t be recovered and the financial aid records that can’t be produced.

So, while the jokes about it being a “report card” are lighthearted, it’s actually much higher stakes than that. State regulators, school boards, union leaders and local taxpayers are all holding schools accountable. Communities work to protect children from harm, and that includes protecting their data.
