What is the best email security solution for a small UK business?

For most small UK businesses, the best email security solution is a layered approach. This usually means advanced email security to reduce phishing, malware and spam, DMARC to protect the business domain, Microsoft 365 security monitoring to find risky settings, identity threat detection to spot account compromise, and cloud backup so the business can recover if something goes wrong.

What is anti phishing for small business?

Anti phishing for small business means putting controls in place to reduce the chance of staff receiving or acting on fake emails. This can include email filtering, malicious link protection, attachment scanning, DMARC, staff awareness, account monitoring and clear reporting processes.

How do I stop phishing emails reaching my staff?

You can reduce phishing emails reaching staff by using dedicated email security, tightening Microsoft 365 security settings, applying DMARC, SPF and DKIM to your domain, monitoring suspicious account activity and training staff to report suspicious messages. No system blocks every phishing email, so the aim is to reduce risk and add layers of protection.

What is business email protection in the UK?

Business email protection in the UK usually covers phishing protection, malware protection, spam filtering, domain spoofing protection, Microsoft 365 security monitoring, identity threat detection and backup. It helps reduce the risk of fraud, account compromise, data loss and business disruption.

Does Microsoft 365 need extra email security?

Microsoft 365 includes built-in security features, but many small businesses still benefit from additional email security. Extra protection can help reduce phishing, malicious attachments, unsafe links, impersonation, risky inbox rules and account compromise.

Do I need DMARC if I already use Microsoft 365?

Yes, DMARC is still useful if you use Microsoft 365. DMARC helps protect your domain from being spoofed by criminals. It works alongside SPF and DKIM to make it harder for attackers to send emails that appear to come from your business.

Does backup help with phishing?

Backup does not stop phishing emails arriving, but it can help recovery if phishing leads to deleted emails, changed files, compromised accounts or data loss. Microsoft 365 backup should be part of a wider email security and recovery plan.

What is the best email security for a UK SME?

The best email security for a UK SME is usually a layered setup that includes phishing and malware protection, DMARC, Microsoft 365 security monitoring, identity threat detection, staff awareness and cloud backup. The right mix depends on how the business uses email, Microsoft 365, cloud files and remote access.

A new face at Black Swan Cyber

Meet
Glitch.

A curious digital troublemaker who lives in the small gaps businesses do not always notice.

Come and meet him See where he hides

Who is Glitch?

Small gaps.
Unexpected consequences.

Glitch is not a hacker. He represents the overlooked details and everyday decisions that can turn into much bigger problems.

The update postponed until tomorrow. The account nobody disabled. The backup nobody tested. The unexpected email that looks completely genuine.

In these stories, the Black Swan is the protector. In real life, Black Swan Cyber is your security partner: helping you understand the gaps, decide what to fix first and choose protection that fits your organisation. We work alongside your IT team and help you make sense of what needs doing next.

Glitch finds the gaps

Curious, clever and just mischievous enough to show what can happen when a small detail is missed.

The Black Swan notices

Calm observation, sensible preparation and a practical response when something unexpected appears.

Glitch makes the gaps visible. Black Swan helps you deal with them.

Where might Glitch be hiding?

Small moments that matter

Each story starts with something perfectly ordinary. A postponed update, an old account or a request that looks genuine.

Updates

Remind me tomorrow

Criminals do not always need to find a new way in. Sometimes the weakness has already been fixed, but the update has not been installed.

Glitch loves an update you will install tomorrow. Especially when tomorrow never comes.

Keep software updated

Old accounts

Dave left six months ago

Nobody deliberately left the door open. Disabling the account simply fell into the gap between HR, management and IT.

When somebody leaves, who checks that all their digital keys have been returned?

Shared passwords

One password. Six people.

Shared credentials make it harder to protect an account and almost impossible to tell who actually used it.

One password. Six members of staff. Absolutely no idea who logged in.

The invoice looks right

The supplier, conversation and email account can all be genuine. A criminal may only need to change the payment details.

Glitch changed one line. Fortunately, somebody checked.

It says the backup worked

A successful notification tells you a process completed. A test restore tells you whether the data is actually useful.

You have a backup. But has anyone checked what is inside it?

Identity

Glitch has the password

Passwords can be stolen, captured or guessed. A second, stronger identity check means the password alone should not be enough.

Glitch knew the password. Fortunately, the password was not enough.

Glitch’s forged invoice

From: Accounts <accounts@yourbusiness.example>

Subject: Updated payment details

Please use our new bank details for your next payment.

Your domain on the message.

Illustrative email using a fictional domain

Domain spoofing

Your email address. His bank details.

Glitch does not always need access to your mailbox. He can try to forge the From address so a message appears to come from your business.

SPF, DKIM and DMARC help receiving email systems check that claim. Properly configured DMARC enforcement asks them to quarantine or reject messages that fail those checks.

Glitch borrowed your email address. The receiving system wanted proof.

Understand SPF, DKIM and DMARC

These checks protect against spoofing your domain. They do not make every email safe or stop fraud from a compromised genuine account.

After hours

Your business went home. Its technology did not.

Email, cloud accounts, websites and laptops do not keep office hours. That is why detecting unusual activity matters as much as trying to prevent it.

Glitch arrived at 2:13am. Fortunately, somebody was watching.
