Passwords alone are no longer enough to protect schools and businesses from modern cyber threats. With phishing attacks, credential theft and AI-powered scams increasing, organisations must strengthen their security beyond a basic login. This guide explains the essential upgrades every school and SME should implement to stay secure in 2026.
For years, passwords were the main barrier protecting organisations from cyber attacks. But modern cyber criminals use automated tools, credential stuffing, password spraying and AI-generated phishing to break into accounts – meaning passwords alone are no longer effective.
At Remedian IT Solutions, we support schools and SMEs across Greater Manchester and the North West. During Microsoft 365 audits, we regularly find environments with strong passwords but critical missing security layers. In today’s threat landscape, relying solely on passwords leaves your organisation exposed.
MFA is the single most effective way to prevent account breaches. It requires staff to verify their identity using something they know (password) and something they have (authenticator app or code).
MFA should be enabled for:
If a password is compromised but MFA is enabled, attackers are stopped. Explore Remedian’s cybersecurity services.
Conditional Access adds smart rules to Microsoft 365 logins, such as requiring MFA when off-site or blocking sign-ins from outside the UK.
Useful examples include:
Without Conditional Access, every login is treated the same — even suspicious ones. See how our managed IT support helps protect your organisation.
Legacy authentication (POP, IMAP, basic auth) does not support MFA and is one of the leading causes of account compromises in schools and SMEs.
Unless absolutely required, these old protocols must be disabled. Where they are still needed, exceptions should be tightly controlled and monitored.
Phishing remains the number one method attackers use to steal passwords. Microsoft Defender adds essential layers of email filtering.
These controls significantly reduce the chance of staff clicking on a malicious link or opening a dangerous attachment.
Even if Microsoft 365 is secure, unsafe devices can still allow attackers in. Modern device security is essential for both schools and SMEs.
A secure cloud account is only as safe as the device accessing it. For schools, this is especially important where devices are shared across classes. Learn how we support school IT environments.
“Anyone with the link” file sharing is one of the biggest causes of accidental data leaks in both schools and businesses.
These changes help prevent sensitive files – such as HR documents, pupil records or financial data – from being accessed by the wrong people.
Microsoft provides availability, not full backup. Accidental deletion, misconfiguration, or ransomware can still cause permanent data loss if you rely solely on Microsoft.
A dedicated backup system is essential for both safeguarding and business continuity. Please find out more about our secure backup services.
Security alerts help spot suspicious activity early, before it becomes a serious incident.
Key events to monitor include:
These alerts should be reviewed regularly – ideally by a managed IT provider who can investigate and resolve issues quickly. See how our proactive IT health monitoring works and how it supports managed IT support.
Schools and businesses face more cyber risks than ever, and passwords alone are no longer enough. With a few focused upgrades, you can dramatically reduce the likelihood of a data breach or account compromise.
