Cyber security for South Hams businesses starts with knowing which threats are realistic for a small firm, such as phishing emails, invoice fraud, account takeover and ransomware, and then putting sensible safeguards in place. We help shops, offices, trades and holiday businesses across Kingsbridge, Salcombe, Dartmouth and Totnes through our cyber security service, which begins with a review of your actual setup rather than a generic checklist.
Proportionate cyber security protection for businesses, organisations and households across South West England, including Kingsbridge, the South Hams, Devon and Cornwall. We identify your real security risks, implement practical safeguards and establish clear, straightforward policies that people can understand and follow. This guide explains the risks we see most often, the protections worth switching on now and what to do if something goes wrong, while our IT support for Kingsbridge businesses covers the day-to-day side.
Which cyber threats are most likely for a small business?
Phishing emails remain one of the most common ways in, and they often look like invoices, delivery notices or messages from a known supplier. Invoice fraud works in a similar way, with a convincing message asking for a payment to be sent to new bank details. Account takeover follows when a stolen password unlocks email, which in turn unlocks everything connected to it.
Ransomware locks files until a payment is demanded, and it usually arrives through an email attachment, a fake download or an unpatched device. Lost or stolen laptops and phones are often overlooked, yet they can expose client details or saved passwords. Knowing these risks makes the safeguards that follow much easier to justify to your team.
- Phishing: messages that imitate banks, couriers or suppliers.
- Invoice fraud: last-minute requests to change payment details.
- Account takeover: a reused or leaked password on email.
- Ransomware: files locked until a payment is demanded.
- Lost devices: laptops or phones with unlocked storage.
Why should I switch on multi-factor sign-in?
Multi-factor sign-in asks for a second confirmation, such as an approval on a phone or a code from an app, after the password has been entered. It stops many attacks that rely only on a stolen password, which is why it is one of the most useful steps a small business can take. Turn it on for email, banking, accounting and any cloud file store first.
Use an authenticator app or a security key where possible rather than text messages, which can be intercepted. Make sure staff know what a genuine prompt looks like, and never approve a sign-in request they did not start themselves. We can help set this up across Microsoft 365 and other common services without disrupting the working day.
How should devices and software be kept up to date?
Software updates close security holes that attackers already know about, so delaying them leaves a door open. Operating systems, browsers, accounting software and router firmware all need regular attention, and many can be set to update automatically. Old or unsupported devices carry a risk of their own and should be replaced rather than patched indefinitely.
Endpoint protection, meaning security software running on each laptop and desktop, adds a layer that watches for suspicious files and behaviour. Choose a well-known product that can be managed centrally, so one person can see the status of every device. Keep it running, and check that alerts are reviewed rather than ignored.
- Turn on automatic updates for operating systems and browsers.
- Replace devices that no longer receive security updates.
- Keep router and firewall firmware current.
- Use managed endpoint protection that reports on every device.
How should backups be kept safe?
A backup is only useful if it can be restored, and it is only safe if ransomware cannot reach it. Keep at least one copy separate from your everyday network, such as an external drive that is disconnected once the backup has run, or a cloud copy with its own sign-in. Test a restore now and then so you know the process works when it is needed.
Make sure the backup covers the files, email and accounting data the business relies on, not just the desktop. Note where each copy is kept and who can access it. A backup that nobody checks tends to fail quietly, so review it at regular intervals and record the result.
What about staff habits and simple policies?
Most incidents begin with a person clicking a link, approving a payment or sharing a password, so staff habits matter as much as software. Keep the rules short and practical: check any unexpected payment request by phoning a number you already know, never share passwords by email, and report anything odd straight away. People follow rules they understand, so explain the reasons behind each one.
A one-page policy covering passwords, devices, email and reporting is usually enough for a small team. Review it when you add a new system or a new member of staff. Our cyber security audit guide for Devon explains how to test whether these policies are working as intended.
What should I do if something goes wrong?
Act quickly but calmly. Disconnect the affected computer from the network, including Wi-Fi, and do not switch it on again until someone has checked it. Do not pay any demand or follow instructions in a message that asks for money. Write down what happened, when it happened and what was clicked or shared, because that record helps whoever investigates.
Change the passwords for affected accounts from a different, clean device, and tell your bank if payment details may have been exposed. Then have a specialist check the wider network, because one infected machine often points to others. Use the contact page to get in touch if you want help with a response or a review of your current safeguards.
