CYAN IT on the Front Line: The Most Common IT Support Issues in 2025 and Beyond

 

If 2015 was “don’t click that link,” then 2025 onwards is “don’t click that link, don’t paste that command, and also… why is your cloud identity trying to log in from three continents at once?” The modern IT support queue is less “my printer won’t print” and more “my business is one dodgy login away from a very bad week.”

That’s why London organisations lean on partners like CYAN IT: an IT service provider supporting businesses across London and Kent, covering everything from infrastructure and procurement through to Microsoft 365 migration and ongoing support, with an emphasis on clear communication instead of jargon.

Here are the most common IT support issues CYAN IT and many providers are tackling in 2025 and onwards, and what smart businesses do about them.

 

1) Phishing and account takeover (still the “Number One Villain”)

Phishing remains the most prevalent breach or attack type for UK organisations, and it’s still the most disruptive when it lands.

What’s changed is the polish: Microsoft reports that AI is scaling and sharpening social engineering, making attacks faster and more convincing.

Support impact: password resets, compromised mailboxes, fraudulent payment attempts, and incident response.

How CYAN IT helps: strengthening Microsoft 365 security (MFA, conditional access, safer configurations), hardening email and identity controls, and guiding users with practical, plain-English advice.

2) New social engineering tricks (Teams, “ClickFix,” and inbox smokescreens)

Microsoft highlights emerging techniques like ClickFix (tricking users into pasting commands) and attacks that pivot into collaboration tools like Teams.

Microsoft is also pushing “secure-by-default” protections in Teams starting January 2026, reflecting how collaboration platforms have become a prime target.

Support impact: unusual device behaviour, malware cleanup, and urgent containment work.

How CYAN IT helps: proactive support tooling and fast remote troubleshooting, plus guidance on safer working patterns that don’t cripple productivity.

3) Windows 10 end of support and the upgrade squeeze

Windows 10 support ended 14 October 2025. That’s a big deal for businesses still running older hardware, because unpatched endpoints become easy stepping stones for attackers.

Support impact: upgrade projects, compatibility headaches, and urgent device procurement.

How CYAN IT helps: procurement and rollout planning, plus infrastructure support to migrate users smoothly to modern, supported setups.

4) Cloud misconfiguration and identity sprawl

Cloud isn’t “set and forget.” Weak identity and access management remains a common risk area, especially when permissions multiply across apps and services.

Support impact: data exposure risk, admin lockouts, and messy tenant cleanups.

How CYAN IT helps: Microsoft 365 tenant management, licensing support, structured migrations, and ongoing maintenance so the cloud stays orderly and secure.

5) SaaS sprawl and shadow AI

Teams sign up for tools with a card and an email address, then IT gets asked to “make it secure” after the fact. SaaS sprawl and shadow IT are still rising concerns, amplified by the rapid adoption of AI tools.

Support impact: fragmented logins, data governance gaps, surprise renewals, and security blind spots.

How CYAN IT helps: bringing order to the chaos with sensible governance, centralised Microsoft 365 foundations, and a support approach that keeps people productive while reducing risk.

WHAT SHOULD London businesses DO THEN?

In 2025, 2026 and beyond, the most common IT support issues orbit one theme: identity, cloud, and human-factor attacks moving at machine speed. The fix is rarely one product. It’s consistent management, proactive support, and security that’s usable.

That’s the lane CYAN IT aims to own: practical IT support, modern Microsoft 365 capability, and clear communication that helps London teams stay focused on work, not firefighting.
