How Often Should You Train Employees on Cybersecurity Awareness in 2026?

Cybersecurity awareness training used to be something many businesses completed once a year.

Employees watched a presentation, answered a few questions, ticked a box and then largely forgot about cyber security until the same exercise came around 12 months later.

That approach no longer reflects the threat environment businesses face in 2026.

Phishing remains the most common cyber attack identified by UK businesses. The Government's Cyber Security Breaches Survey 2025/26 found that 38% of businesses experienced phishing during the previous 12 months, while 43% identified some form of cyber breach or attack.

At the same time, criminals are becoming better at creating believable emails, fake login pages, payment requests and impersonation attempts. Generative AI is making social engineering easier to scale and more convincing. The NCSC assesses that AI will continue increasing the effectiveness and frequency of cyber threats through 2027.

So, how frequently should you train employees?

The answer isn't once a year.

It also isn't necessarily every four months.

In 2026, the better approach is continuous cybersecurity awareness supported by regular short training, practical reminders and additional training when risks change.

There Is No Magic Training Interval

Older cyber-awareness advice often tries to identify a single perfect interval.

Every three months.

Every four months.

Every six months.

But cybersecurity awareness does not work like an MOT certificate.

An employee doesn't suddenly become secure immediately after completing training and then become unsafe exactly 120 days later.

The NCSC recommends ongoing reminders and top-up training to maintain skills, using different formats such as briefings, online courses, blogs and simulated cyber attacks rather than depending on one annual event.

That is a much more sensible approach.

Instead of asking:

“When is our annual cyber training?”

businesses should ask:

“How are we keeping security awareness fresh throughout the year?”

A Practical Cybersecurity Training Schedule for SMEs

For many SMEs, a sensible 2026 programme could look something like this.

When an Employee Joins

Cybersecurity awareness should form part of onboarding.

New employees should understand your organisation's basic security expectations before they begin handling sensitive information.

That could cover:

Phishing and suspicious messages.

Microsoft 365 security.

Multi-factor authentication and passkeys.

Password managers.

Company devices.

Remote working.

Handling customer information.

How to report something suspicious.

It should also explain what employees are expected to do if they think they have made a mistake.

That last point is extremely important.

Provide Short Refreshers Throughout the Year

Instead of another hour-long presentation every few months, use smaller interventions.

For example, a business might provide a short cyber-awareness update every quarter covering one or two relevant topics.

January might cover phishing.

April could look at Microsoft 365 account compromise.

July might cover payment fraud and impersonation.

October could focus on ransomware and reporting suspicious activity.

That doesn't mean quarterly training is a mandatory standard.

It is simply a practical way of keeping cyber security visible without overwhelming employees.

Short, relevant reminders are usually easier to absorb than repeatedly giving everybody the same lengthy presentation.

Train People When the Threat Changes

Cyber training shouldn't operate independently from what is happening in the real world.

If your organisation suddenly sees a wave of convincing phishing messages pretending to come from Microsoft, tell employees.

If criminals are impersonating one of your suppliers, warn the people who deal with that supplier.

If a new QR-code phishing technique starts appearing, explain it.

Training becomes much more useful when employees can immediately connect it to something they may actually encounter.

The NCSC's guidance supports combining different awareness methods rather than relying on one standardised training event.

Phishing Training Needs to Change in 2026

For years, employees were taught to identify phishing by looking for:

Poor spelling.

Strange grammar.

Bad logos.

Obvious formatting mistakes.

Those warning signs still exist.

But they are nowhere near enough anymore.

AI can help criminals produce messages that are grammatically correct, professionally written and tailored to the target. The NCSC has specifically highlighted the increasing role of generative AI in creating convincing social-engineering material.

Modern phishing training should therefore concentrate more on behaviour and context.

Teach employees to ask:

Was I expecting this request?

Why am I being asked to log in again?

Is somebody creating artificial urgency?

Why have these payment details suddenly changed?

Can I verify this request another way?

A perfectly written email can still be malicious.

Include Microsoft 365 Login Scams

Microsoft 365 accounts are extremely valuable to attackers.

A compromised mailbox can potentially expose business conversations, documents, invoices and customer information.

Employees should therefore recognise suspicious login pages.

Useful training examples can demonstrate:

Fake Microsoft sign-in pages.

Unexpected password-reset requests.

Suspicious MFA prompts.

Fraudulent shared-document notifications.

Fake SharePoint or OneDrive links.

Employees should also understand that MFA prompts they did not initiate should not simply be approved.

And as businesses move towards passkeys and phishing-resistant authentication, awareness training should explain why the login experience may be changing.

Don't Forget QR-Code Phishing

QR codes have become common in offices, restaurants, parking systems, authentication workflows and marketing.

Criminals know that too.

A QR code can conceal the destination URL from the user until it is scanned, which makes it useful for phishing.

Employees should be cautious about unexpected QR codes arriving by email or appearing on documents that encourage them to authenticate urgently.

The same rule applies:

Unexpected authentication requests deserve suspicion, regardless of whether they arrive as a hyperlink or QR code.

Train Employees About AI and Impersonation

Another growing issue is impersonation.

Employees should understand that convincing written communication is no longer strong evidence that a message genuinely came from the claimed sender.

Generative AI can assist attackers with convincing text, while synthetic audio and imagery can increase the sophistication of impersonation attempts. The NCSC has been actively examining AI-generated phishing and deepfakes as part of the evolving social-engineering threat.

This is particularly important for finance teams and senior management.

If somebody requests:

A large payment.

A change of bank details.

Sensitive information.

A password reset.

A new administrator account.

employees should have a separate verification process.

For example, confirm significant payment changes using a trusted telephone number already held on record.

Don't verify the request using the telephone number conveniently supplied inside the suspicious email.

Give High-Risk Teams Additional Training

Not everybody in the organisation faces exactly the same risk.

Finance employees may deal with payment fraud.

HR teams handle sensitive employee information.

IT administrators have privileged access.

Directors can be attractive impersonation targets.

Reception employees may receive unexpected calls asking for information.

Training should therefore be role appropriate.

The NCSC specifically recommends providing cyber-security skills appropriate to people's roles and how they genuinely use systems.

An accounts employee needs more detailed training around invoice fraud than somebody who never processes payments.

An IT administrator needs far more knowledge about privileged access and phishing-resistant authentication than an ordinary office user.

What About Phishing Simulations?

Simulated phishing can be useful.

It can help identify where additional awareness or technical protection may be needed.

But simulations should be used carefully.

Turning them into an exercise where employees are publicly embarrassed for clicking the wrong email can actually damage security.

The NCSC warns that poorly handled phishing simulations can erode trust and discourage employees from reporting mistakes. It recommends creating a positive cyber-security culture where people feel comfortable reporting suspicious incidents.

That is crucial.

The objective should be:

“Let's understand where we need to improve.”

Not:

“Let's catch Dave from accounts doing something stupid.”

Make Reporting Easy

One of the most valuable things an employee can do is report something suspicious quickly.

Imagine an employee clicks a phishing link and enters their Microsoft 365 password.

Two possibilities follow.

Scenario One

They immediately tell IT.

The account can be investigated, sessions revoked, credentials secured and other employees warned.

Scenario Two

They're embarrassed.

They say nothing.

The attacker potentially has hours or days to explore the account.

Which business would you rather be?

The NCSC's cyber-security culture principles emphasise creating an environment where employees can ask for help, report issues and admit mistakes.

Fast reporting can be far more valuable than pretending employees will never make mistakes.

Senior Management Needs Training Too

Cybersecurity policies should not magically stop applying when somebody becomes a director.

In fact, executives often have access to particularly valuable information.

They can also be attractive impersonation targets because employees may feel pressured to respond quickly to requests apparently coming from senior management.

The NCSC stresses that leaders should model secure behaviours and avoid undermining security controls by expecting special treatment.

If the managing director routinely bypasses MFA or asks employees to ignore payment verification procedures because they're “in a rush”, staff quickly learn that security rules are optional.

Leadership behaviour matters.

Measure Behaviour, Not Just Completion Rates

A training dashboard saying:

100% COMPLETE

looks excellent.

But did behaviour actually improve?

Useful measurements might include:

How quickly employees report suspicious messages.

Whether repeat phishing mistakes decrease.

Which departments need additional support.

Whether people recognise suspicious authentication requests.

Whether financial verification procedures are being followed.

Whether employees understand how to contact IT.

Completion rates tell you whether somebody opened the training.

They don't necessarily tell you whether your organisation has become more secure.

The NCSC's 2025 cyber-security culture guidance explicitly encourages organisations to look beyond purely educational approaches and consider the wider culture influencing employee behaviour.

Technology Must Support Your Employees

Another important point:

Employees should not be expected to defeat every cyber attack themselves.

Training is one layer.

Your technical controls should provide others.

That can include:

Phishing-resistant MFA and passkeys.

Microsoft Defender and EDR.

Email security.

DNS and web filtering.

Conditional Access.

Managed devices.

Rapid patching.

Least-privilege access.

Secure backups.

The NCSC's phishing guidance specifically recommends a layered approach rather than relying solely on employees spotting malicious messages.

Your staff should be part of your cyber defence.

They should not be the entire cyber defence.

So, How Often Should Cybersecurity Training Happen?

A useful 2026 approach for many businesses would be:

Initial cybersecurity training during employee onboarding.

Short awareness refreshers throughout the year — quarterly can be a practical starting point.

Additional training when important threats or business processes change.

Role-specific training for high-risk employees.

Regular security reminders and communications.

Carefully designed phishing simulations where appropriate.

Immediate learning after genuine incidents or near misses.

Then review whether the programme is actually changing behaviour.

The important point is that cyber awareness becomes continuous, rather than an annual event employees forget about the following week.
