IT problems affect businesses of every size, but the picture in Kent has its own shape. There are 65,370 enterprises in the county and 90% of them employ fewer than ten people. Almost all the rest are small as well, with 98.2% employing under fifty (Kent County Council, ONS UK Business Counts, March 2025). Most Kent businesses therefore run without dedicated IT staff, and the controls that prevent everyday disruption are the ones smallest firms are least likely to have.
The government’s Cyber Security Breaches Survey 2025/2026 found that 43% of UK businesses identified a breach or attack in the previous twelve months. That rises to 65% of medium businesses and 69% of large ones. Only 25% of businesses have a formal incident response plan, 30% carry out a cyber security risk assessment, and 19% run staff awareness training. Most avoidable downtime sits in that gap.
A proactive IT strategy reduces disruption, protects business data and supports growth. Regular IT assessments, software updates, secure backups and effective cyber security measures prevent many problems before they reach your operations. Below are the ten IT issues we are asked about most often by businesses across Kent, what the evidence says about each, and what actually fixes them.
Network Security and Data Breaches
Issue: Businesses in Kent can be vulnerable to cyberattacks, ransomware and data breaches.
The threat has changed shape over the past few years. Phishing is now the most common attack by a wide margin, affecting 38% of all businesses, and 69% of those hit named it the most disruptive attack they faced. Ransomware has gone the other way, falling to 1% of businesses from 3% two years earlier. For most Kent firms the realistic risk is someone impersonating a supplier, a client or a director convincingly enough to get paid.
In our experience the incidents that cost real money usually begin with a stolen password rather than a virus. An invoice gets redirected after somebody has quietly been reading a mailbox for a fortnight.
Solution: Use managed firewalls, multi-factor authentication, endpoint protection and regular patching. MFA on email gives a small business more protection for less money than anything else on this list. Train staff to recognise phishing attempts and other common cyber threats, and review your security controls regularly.
Data Backup and Recovery
Issue: Hardware failure, human error and cyberattacks can result in data loss.
74% of businesses back up data to a cloud service, but cloud storage on its own is not a backup. The NCSC makes the point clearly in its guidance on ransomware-resistant backups. If an attacker holds valid credentials, any backup those credentials can reach is a backup they can delete. At least one copy needs to be offline or immutable.
The assumption we correct most often is that Microsoft 365 backs itself up. It does not. Retention is not the same as recovery, and once the retention window closes, deleted or encrypted data is gone. Our guide to external backups for Microsoft 365 explains why.
Solution: Keep secure on-site and off-site backups, with at least one immutable or offline copy. Test your recovery procedures regularly. A backup nobody has ever restored from is an assumption rather than a safeguard.
Slow Internet Connection
Issue: Slow or unreliable internet can reduce productivity and interrupt essential business services.
Kent’s geography matters here. Ofcom’s Connected Nations 2025 report puts full-fibre availability at 81% of urban premises against 60% of rural ones. For gigabit-capable connections the gap is wider still, at 92% against 61%. A business in Dartford and a business out on the Weald are not working with the same infrastructure, so advice written for one is often useless to the other.
Most of the slow internet complaints we investigate turn out to be ageing Wi-Fi access points or an unmanaged switch rather than the line itself. Where fibre genuinely is not available, bonded connections or a properly specified 4G or 5G failover will usually solve it.
Solution: Review your broadband connection, Wi-Fi coverage, network equipment and bandwidth usage before assuming you need a faster line. Upgrade connectivity where it is genuinely needed, prioritise your critical applications, and make sure anything that cannot stop has a failover. Our IT support in Kent team can audit all four in a single visit.
Outdated Hardware and Software
Issue: Outdated technology can create inefficiencies, compatibility issues and security vulnerabilities.
This stopped being theoretical on 14 October 2025, when Windows 10 reached end of support. Any machine still running it receives no security updates unless it is enrolled in Microsoft’s Extended Security Updates programme, which is a paid stopgap rather than a plan. Unpatched vulnerabilities build up month by month.
We still find Windows 10 machines running at Kent client sites. They are rarely the main fleet. Usually it is a handful of forgotten endpoints, such as a reception PC or a machine driving a label printer, and those are exactly the ones that get missed in a refresh.
Solution: Keep operating systems, software and devices current through a planned maintenance and replacement schedule, and hold an accurate asset inventory so nothing drops off it. Set an IT budget that pays for upgrades on your timetable instead of during an emergency. See our guidance on Windows end of life.
Scalability Challenges
Issue: As a business grows, its existing IT infrastructure may no longer meet its needs.
With 90% of Kent enterprises employing fewer than ten people, the typical scaling event in the county is not dramatic growth. It is going from six staff to fifteen and finding that arrangements which worked informally now fail every week. Shared logins, a single on-premise server and file storage that nobody administers all tend to break at roughly the same headcount.
We see this bite hardest between ten and thirty staff. Identity and file access give way first, well before anyone runs short of storage or processing power.
Solution: Invest in systems that scale, such as cloud services, virtualisation and flexible licensing, so your technology can adapt as the team and the workload grow. Put proper identity management in place before you need it.
Compliance and Regulatory Issues
Issue: Failure to meet industry-specific legal, regulatory or data protection requirements can create financial and reputational risks.
Under UK GDPR a notifiable personal data breach has to be reported to the ICO within 72 hours. The ICO’s 72-hour guidance is clear that the clock starts when you become aware of the breach, not when you finish investigating it. Set that against the 25% of businesses holding a formal incident response plan, and most organisations would still be working out how to report while the deadline ran down.
Among the regulated Kent sectors we work with most, including solicitors, financial services, care homes and schools, the compliance problem is rarely the security control itself. It is being unable to show the control was working on the day in question.
Solution: Identify the regulations that apply to your business, put suitable controls in place, and keep auditable records of them. Review everything regularly so your compliance can be demonstrated rather than assumed. Our GDPR overview is a useful starting point.
Employee Training
Issue: Employees may not have the knowledge or confidence to use technology securely and effectively.
Only 19% of UK businesses ran staff training or awareness activity last year, and that figure has not moved since the previous survey. Phishing causes the most disruptive attacks by a clear margin, so this is the widest gap in the data between a well-understood threat and a cheap way of reducing it.
Short and frequent works better than long and annual. The businesses that improve are the ones running ten-minute refreshers and the occasional simulated phishing email, rather than booking a half-day course once a year and treating it as done.
Solution: Provide ongoing IT and cyber security training alongside everyday support, and make reporting a suspicious email easy and blame-free. Our staff guide on how to spot spam and phishing emails is a good place to start. External IT specialists can help where in-house expertise is limited.
Mobile Device Management
Issue: Business mobile devices can create security and support challenges, particularly for hybrid and remote teams.
Hybrid working made the company boundary portable, and in most small businesses it also made it invisible. Company data now sits on personal phones that IT has never seen, cannot patch and cannot wipe.
The point where this becomes real is almost always somebody leaving. If a former employee’s personal phone still has a live company mailbox on it the following week, that is a data protection problem as much as an IT one.
Solution: Use Mobile Device Management to configure, secure and monitor company data on both company-owned and personal devices, and to remove it remotely when someone leaves. Microsoft 365 Business Premium includes the tooling for this, and our guide to building a secure remote working setup covers the wider configuration.
IT Support and Help Desk
Issue: Inadequate IT support can prolong downtime and prevent employees from working effectively.
In a ten-person business, one person unable to work is 10% of the company stopped. Small firms feel downtime out of proportion to their size, which is why informal arrangements stop working earlier than most owners expect.
The question worth asking a provider is not how quickly they answer the phone, but what they were doing before you called. With proactive monitoring, most issues are dealt with before anyone raises a ticket.
Solution: Use a responsive managed service provider or an in-house help desk with clear escalation routes, proactive monitoring and defined response times. Cortec has provided IT support across Kent and the South East since 2003, with local teams covering Dartford, Bexley and Tonbridge and Malling.
Disaster Recovery Planning
Issue: Without a tested disaster recovery plan, an IT emergency can cause significant disruption.
Only 25% of businesses have a formal incident response plan and only 30% have carried out a cyber risk assessment. A plan that exists as a document but has never been rehearsed usually fails at the same two points. Nobody can reach the person who holds the credentials, and nobody has checked how long a full restore actually takes.
Two questions decide most of the detail. How much data can you afford to lose, and how long can you afford to be down? Most businesses have never been asked, and the answers tend to surprise whoever has to sign them off.
Solution: Create and maintain a disaster recovery plan covering data restoration, hardware replacement, emergency contacts, communication procedures and responsibilities. Test it at least once a year against a realistic scenario.
IT Consultancy
Many Kent businesses try to manage IT entirely in-house, and it often results in inefficient systems, higher costs and avoidable security risks. Across the ten issues above the pattern is fairly consistent. The technology is seldom the difficult part. What separates the businesses that cope from the ones that struggle is whether somebody owns the problem in advance: the patching schedule, the restore test, the leaver process, the plan nobody has read.
An experienced IT consultancy can identify weaknesses early, build a practical technology roadmap and make sure your IT supports long-term growth. If you would like a clear view of where your business stands against the ten issues above, request a quick quote or book a free IT support consultation.
Frequently Asked Questions
What is the most common IT problem for small businesses in Kent?
Phishing and email-based fraud. The Cyber Security Breaches Survey 2025/2026 found that phishing affected 38% of UK businesses and was the most disruptive attack for 69% of those hit. Because 90% of Kent’s 65,370 enterprises employ fewer than ten people, most have no dedicated IT staff to catch it. Multi-factor authentication and short, regular staff training are the two highest-value first steps.
Is Microsoft 365 backed up automatically?
No. Microsoft 365 provides retention, not backup. Retention policies run for a limited period, and anything deleted or encrypted before you notice can be lost permanently once that period ends. The NCSC recommends keeping at least one backup copy offline or immutable, so an attacker with valid credentials cannot destroy it.
How quickly must a data breach be reported to the ICO?
Within 72 hours of becoming aware of a notifiable personal data breach. The ICO is clear that the deadline runs from the point of awareness rather than from the end of your investigation, so you may need to report while the facts are still being established.
What happens if my business is still running Windows 10?
Windows 10 reached end of support on 14 October 2025. Devices still running it receive no security updates unless they are enrolled in Microsoft’s paid Extended Security Updates programme, so unpatched vulnerabilities build up month by month. ESU is a temporary bridge while you plan replacements.
When should a small business outsource its IT support?
Usually between ten and thirty staff, when informal arrangements start to fail. The practical signals are shared logins, no asset inventory, no tested restore, and no set process for removing access when someone leaves. At that size one person unable to work is a significant share of the business, so response times and proactive monitoring begin to pay for themselves.
