What Good Cyber Hygiene Looks Like in 2026

Cyber Security Awareness Month is a timely reminder that keeping your organisation secure doesn't always require complicated technology. Sometimes, it's the everyday habits that make the biggest difference.

Cyber threats continue to change, with artificial intelligence (AI) creating new opportunities for businesses but also giving cyber criminals more ways to target organisations. From increasingly convincing phishing emails to attacks designed to exploit weak passwords and outdated systems, businesses face a wide range of security challenges.

However, while the threats may be evolving, the foundations of good cyber security remain largely the same.

This October, as part of Cyber Security Awareness Month, we're exploring The Good, The Bad, The AI and what organisations can do to build stronger security habits.

So, what does good cyber hygiene actually look like in 2026, and where should businesses be focusing their attention?

What Is Cyber Hygiene and Why Does It Matter?

Cyber hygiene refers to the everyday practices, processes and behaviours that help keep an organisation's systems, devices and information secure.

Much like maintaining good personal hygiene, cyber hygiene is about consistency. It's not enough to introduce security measures once and assume everything will remain protected. Businesses need to regularly review their approach, address weaknesses and make sure employees understand their role in keeping information secure.

Good cyber hygiene can help organisations:

• Reduce the likelihood of common cyber attacks.

• Protect sensitive business and customer information.

• Identify and address security weaknesses before they become bigger problems.

• Build employee confidence when recognising potential threats.

• Support business continuity and reduce unnecessary disruption.

The challenge for many organisations isn't necessarily knowing that cyber security matters. It's making sure the right practices are followed consistently across the business.

1. Strong Passwords Are Still Essential

Passwords have been a fundamental part of cyber security for years, yet weak, reused and compromised credentials continue to create opportunities for attackers.

Employees often manage multiple accounts across different platforms, making it tempting to reuse familiar passwords or choose something easy to remember.

However, if one account becomes compromised, reused credentials could give an attacker access to several other systems.

Good password hygiene means encouraging employees to use strong, unique passwords for every account and avoiding predictable combinations or personal information.

Businesses should also consider using password managers to help employees securely generate and store their credentials without having to remember every password individually.

What good looks like:

• Using strong, unique passwords for different accounts.

• Avoiding password reuse across personal and business platforms.

• Encouraging the use of reputable password managers.

• Changing passwords promptly when there is evidence of compromise.

Strong passwords remain important, but they shouldn't be the only thing standing between an attacker and sensitive business information.

2. Make Multi-Factor Authentication Part of Everyday Security

Multi-factor authentication (MFA) adds another layer of protection by requiring users to verify their identity through more than one method.

Even if a cyber criminal manages to obtain someone's password, MFA can make it significantly harder for them to access an account.

For organisations managing sensitive information, customer records or cloud-based systems, this additional security measure can make a meaningful difference.

However, simply making MFA available isn't always enough. Businesses should ensure it's enabled wherever possible, particularly for email accounts, remote access, administrator accounts and systems containing sensitive information.

Phishing-resistant MFA methods, such as passkeys or security keys, can offer stronger protection against certain attacks.

What good looks like:

• Enabling MFA across business-critical systems and applications.

• Prioritising stronger authentication methods where available.

• Reviewing accounts that do not currently have MFA enabled.

• Helping employees recognise suspicious authentication requests.

MFA is one of the most practical ways organisations can strengthen their protection against account compromise.

3. Keep Software, Devices and Systems Updated

Software updates aren't always convenient, especially during a busy working day. However, delaying them can leave organisations exposed to known security vulnerabilities.

Cyber criminals regularly look for weaknesses in outdated software, operating systems and applications. Once vulnerabilities become publicly known, attackers may attempt to exploit them before businesses have applied the necessary fixes.

Good cyber hygiene means treating updates as an ongoing security responsibility rather than something that can be put off indefinitely.

This includes everything from employee laptops and mobile devices to business applications, servers and network equipment.

What good looks like:

• Enabling automatic security updates wherever appropriate.

• Prioritising critical security patches.

• Keeping an accurate record of devices and software used across the business.

• Removing unsupported applications and systems that no longer receive security updates.

• Regularly reviewing whether updates have been successfully applied.

By keeping systems up to date, organisations can reduce unnecessary exposure to vulnerabilities that may already have a known fix.

4. Recognise That Phishing Has Changed

Phishing remains a common way for cyber criminals to target businesses. However, the warning signs employees may have relied on in the past aren't always as obvious in 2026.

Previously, phishing emails were often associated with poor spelling, unusual wording and suspicious-looking messages.

Today, AI tools can help attackers produce more convincing communications, with professional language, realistic branding and messages that appear relevant to the recipient.

This means employees can no longer rely on spotting spelling mistakes or obvious errors to identify a potential scam.

Instead, organisations need to encourage a culture where unusual requests are questioned, even when they appear legitimate.

For example, an unexpected email requesting an urgent payment, a password reset or the sharing of sensitive information should always be treated carefully.

What good looks like:

• Checking email addresses and website links before taking action.

• Being cautious of unexpected attachments and requests for information.

• Verifying unusual financial or sensitive requests through a separate, trusted communication channel.

• Encouraging employees to report suspicious messages without hesitation.

• Providing regular awareness training and realistic phishing simulations.

As phishing becomes more convincing, employee awareness and effective verification processes are increasingly important.

5. Understand How AI Is Being Used Across the Business

One of the biggest changes in recent years is how quickly AI has become part of everyday working life.

Employees are using AI-powered tools to draft emails, summarise documents, support customer interactions, analyse information and complete routine tasks.

While these technologies can offer significant benefits, they also introduce new considerations around how information is shared, stored and processed.

For example, employees may unintentionally enter confidential business information into an AI tool without understanding how that information will be handled.

Businesses may also adopt AI-powered services without fully assessing their security settings, access permissions or potential vulnerabilities.

Good cyber hygiene in 2026 therefore needs to extend beyond traditional systems and include the responsible use of AI.

What good looks like:

• Understanding which AI tools are being used across the organisation.

• Establishing clear guidelines on what information can and cannot be shared with AI systems.

• Reviewing the security and privacy considerations of new AI tools before introducing them.

• Training employees to recognise the limitations and potential risks of AI-generated content.

• Testing AI-powered systems to understand whether their security controls work as intended.

AI security doesn't need to be treated as a completely separate conversation. Instead, it should become part of the organisation's wider approach to cyber security and risk management.

6. Make Cyber Security Everyone's Responsibility

Technology plays an essential role in protecting businesses, but employees are just as important.

An organisation can invest in security tools and introduce strong policies, yet still be exposed if employees don't understand how to apply those measures in their everyday work.

This is why good cyber hygiene needs to become part of the wider workplace culture.

Employees should feel confident identifying potential security concerns, asking questions and reporting suspicious activity without worrying about being blamed for making a mistake.

Cyber security awareness shouldn't be limited to a single training session or an annual reminder.

Instead, businesses should look for opportunities to reinforce good habits throughout the year.

What good looks like:

• Providing regular, practical cyber security training.

• Making security policies clear and easy to understand.

• Encouraging employees to report mistakes or suspicious activity quickly.

• Sharing examples of common threats and how to respond.

• Ensuring leaders demonstrate good security practices themselves.

When cyber security becomes a shared responsibility, organisations are better placed to identify potential issues early and respond effectively.

7. Regularly Review and Test Your Security Measures

Good cyber hygiene isn't just about introducing the right controls. It's also about checking whether those controls continue to work.

As businesses grow, adopt new technologies and change the way they operate, their security requirements can change too.

New employees, software platforms, cloud services and AI-powered tools can all introduce additional risks if they aren't properly managed.

Regular security reviews help organisations understand where weaknesses may exist and whether their current approach remains appropriate.

This can include vulnerability scanning, penetration testing, reviewing access permissions and assessing how well employees recognise potential threats.

Businesses should also regularly review their backup and incident response arrangements to ensure they can recover effectively if something does go wrong.

What good looks like:

• Reviewing security controls and access permissions regularly.

• Identifying vulnerabilities and addressing them according to risk.

• Testing systems and applications for potential weaknesses.

• Maintaining secure, recoverable backups and testing restoration procedures.

• Reviewing incident response plans so employees understand what to do if an attack occurs.

Cyber security is an ongoing process. Regular reviews and testing can help businesses understand whether their security measures are keeping pace with changing risks.

The Good, The Bad, The AI: Building Better Security Habits

This Cyber Security Awareness Month, our theme, The Good, The Bad, The AI, highlights an important point: while technology and cyber threats continue to evolve, the everyday foundations of cyber security still matter.

The Good: Businesses have access to practical security measures, greater awareness and technologies that can help them protect their systems and information.

The Bad: Weak passwords, missed updates, phishing attempts and poor security habits can still create opportunities for cyber criminals.

The AI: Artificial intelligence is changing how organisations work and how attackers operate, making it increasingly important for businesses to understand and manage the associated risks.

The key is finding the right balance between maintaining strong security fundamentals and adapting to new challenges.

Organisations don't need to overhaul their entire approach overnight. Small, consistent improvements can make a meaningful difference when they're supported by the right policies, people and processes.
