A lot of small business owners assume hackers are after bigger fish. Banks, retailers, the names you see in the news.
Sadly, that’s not how it works. Most attacks are automated. They scan for weak passwords, old software and open doors, and they don’t care if you employ five people or five hundred.
For firms around Angel, Upper Street and Highbury, good cyber security Islington businesses can depend on is less about expensive tools and more about doing the basics properly.
Why SME Cyber Security Is Different
SME cyber security comes with its own challenges. You probably don’t have a security team. Your staff wear several hats. Budgets are real, so every pound has to earn its place. The good news is that most attacks on small firms succeed through a handful of common gaps. Close those and your cyber risk drops sharply.Priority One: Lock Down Logins
Stolen passwords sit behind a huge share of breaches. Someone reuses a password, it leaks from another website, and an attacker walks straight into their inbox. Multi-factor authentication stops most of that. Switch it on for Microsoft 365, your accounts software, online banking and anything holding sensitive data. It’s an afternoon’s work with a huge payoff.Priority Two: Keep Everything Updated
Old software is an open invitation. Attackers know exactly which flaws exist in unpatched versions of Windows, browsers and everyday apps. Set updates to install automatically wherever you can. For anything that can’t, give one person clear ownership. Devices that no longer receive updates should be replaced, not kept “for now”.Priority Three: Protect Your Email
Email is still the front door for most attacks. Fake invoices, spoofed suppliers and dodgy links land in inboxes every day. Good filtering catches most of it before anyone sees it. Setting up SPF, DKIM and DMARC also makes it harder for criminals to pretend to be you.Priority Four: Back Up and Test
Ransomware hurts small firms because many have no clean copy of their data to fall back on. Backups should be automatic, stored away from your main systems, and tested regularly. A backup you’ve never restored from is really just a hope.Priority Five: Put Core Security Controls in Place
The government-backed Cyber Essentials scheme gives you a sensible framework. It’s built around five security controls:- Firewalls
- Secure configuration
- User access control
- Malware protection
- Security update management
