Cybersecurity Protection for Businesses: What You Should Be Doing Now

27 Jul 2026

Cybersecurity is no longer something businesses can afford to treat as a future project.

Cyber criminals are constantly looking for weak passwords, unprotected devices, outdated software, poorly configured cloud services and employees who can be tricked into revealing information. Businesses of every size can be targeted, and smaller organisations are not automatically overlooked.

In many cases, attackers actively seek out businesses with limited internal IT resources because they expect security controls to be weaker.

The good news is that effective cybersecurity does not depend on one expensive product. Strong protection comes from combining practical security measures, good processes, trained employees and ongoing monitoring.

Here is what your business should be doing now.

Start by Understanding Your Current Risks

Before improving your cybersecurity, you need to understand what you are protecting and where your weaknesses may be.

This should include reviewing:

Business devices
Servers and network equipment
Cloud services
Microsoft 365 accounts
Email systems
Remote access
Business applications
Customer and employee data
Backups
User permissions
Third-party suppliers

Many businesses have technology they no longer use, old user accounts that remain active or devices that are not properly managed. These gaps can create unnecessary risk.

A cybersecurity review can help identify which areas need immediate attention and which improvements can be planned over time.

Use Multi-Factor Authentication

Multi-factor authentication, commonly known as MFA, is one of the most important security measures a business can introduce.

A password alone may not be enough to protect an account. Passwords can be stolen through phishing emails, data breaches, malware or password reuse.

MFA requires the user to provide an additional form of verification when signing in. This might include:

An authentication app
A security key
A biometric check
A temporary verification code

Even when a criminal obtains a password, MFA can help prevent them from accessing the account.

MFA should be enabled for:

Microsoft 365
Cloud applications
Remote access systems
Administrative accounts
Financial systems
Password managers
Any service containing sensitive business data

Where possible, businesses should use authentication apps or security keys rather than relying only on text messages.

Strengthen Password Security

Weak and reused passwords remain a major cause of business account compromise.

Employees should not use the same password across multiple systems. If one service is breached, criminals may attempt to use the same credentials elsewhere.

Businesses should introduce a clear password policy that encourages:

Long, unique passwords
No password reuse
Secure storage
Immediate password changes after suspected compromise
Separate administrator credentials

A business password manager can help employees create and store strong passwords without needing to remember each one.

Password managers can also reduce risky habits such as writing passwords down, storing them in spreadsheets or sharing them through email.

Protect Your Business Email

Email is one of the most common entry points for cyber attacks.

Criminals may use phishing emails to steal passwords, deliver malware, impersonate senior employees or trick finance teams into making fraudulent payments.

Business email protection should include:

Advanced spam filtering
Phishing detection
Attachment scanning
Link protection
Multi-factor authentication
Suspicious login monitoring
Restrictions on automatic forwarding
Email authentication controls
User awareness training

Businesses should also configure SPF, DKIM and DMARC for their domain. These technologies help reduce the risk of criminals impersonating your organisation through email.

Keep Devices and Software Updated

Software updates often include fixes for known security vulnerabilities.

When updates are delayed, attackers may be able to exploit weaknesses that already have publicly available fixes.

Businesses should keep the following updated:

Windows and macOS devices
Mobile phones and tablets
Servers
Web browsers
Business applications
Firewalls
Wireless access points
Network switches
VPN software
Cloud applications

Patch management should be monitored rather than left entirely to individual users.

Managed updates help ensure critical patches are applied consistently across the organisation.

Use Modern Endpoint Protection

Traditional antivirus alone may not provide enough protection against current threats.

Modern endpoint protection can detect suspicious activity, isolate infected devices and identify attacks that may not rely on known malware files.

Businesses should consider endpoint detection and response, often shortened to EDR.

EDR can help identify:

Ransomware activity
Suspicious scripts
Unusual account behaviour
Malicious software
Credential theft
Privilege escalation
Attempts to disable security tools

This protection should be installed and actively monitored across all business devices.

Secure Microsoft 365

Microsoft 365 contains some of the most important information within a business, including email, documents, Teams conversations and shared files.

However, the platform must be configured correctly.

Important Microsoft 365 security controls include:

Multi-factor authentication
Conditional Access
Microsoft Defender
Safe Links and Safe Attachments
Restricted administrator access
Audit logging
Data loss prevention
Sensitivity labels
External sharing controls
Mobile device management
Sign-in risk monitoring

Default settings may not provide the level of protection your organisation needs.

A Microsoft Secure Score review can help identify practical improvements and highlight areas where security controls are missing.

Review User Permissions

Employees should only have access to the systems and information they need for their role.

Over time, users often accumulate additional access as they change roles or work on different projects. This is known as privilege creep.

Excessive permissions can increase the damage caused by:

Account compromise
Employee mistakes
Insider threats
Malware
Ransomware

Businesses should regularly review:

Microsoft 365 roles
Shared folders
Cloud application access
Administrator accounts
Financial systems
Customer databases
Remote access permissions

Access should be removed promptly when employees leave the organisation.

Separate Administrator Accounts

Employees who manage systems should not use administrator accounts for normal daily activity.

Administrator accounts have elevated permissions, making them valuable targets for attackers.

A safer approach is to provide separate accounts for:

Everyday work
Administrative tasks

Administrator access should be limited, monitored and protected with strong MFA.

Where possible, businesses should also use just-in-time access, allowing elevated permissions only when they are required.

Back Up Your Data Properly

Backups are essential for recovering from ransomware, accidental deletion, hardware failure and other incidents.

However, simply having a backup is not enough.

A reliable backup strategy should ensure that:

Important data is backed up regularly
Backups are encrypted
More than one copy exists
At least one copy is isolated from the main network
Cloud data is included
Backups are monitored
Recovery is tested

Businesses should know how long recovery would take and which systems must be restored first.

Microsoft 365 should also be considered. Although Microsoft provides resilience for its platform, businesses remain responsible for their own data retention and recovery requirements.

Test Your Backups

An untested backup may provide false confidence.

Businesses should regularly perform recovery tests to confirm that:

The backup can be accessed
Files can be restored
Applications can be recovered
Data is complete
Recovery times meet business requirements

Testing can also reveal configuration problems before a real incident occurs.

Secure Remote Working

Remote and hybrid working have expanded the boundaries of the business network.

Employees may access company data from home, customer sites, hotels or shared workspaces.

Businesses should protect remote workers through:

Managed devices
Multi-factor authentication
Secure VPN or zero-trust access
Endpoint protection
Disk encryption
Mobile device management
Conditional Access
Secure Wi-Fi guidance
Remote support controls

Employees should avoid accessing sensitive business information from unknown or public devices.

Public Wi-Fi should also be treated carefully, particularly when accessing cloud services or financial systems.

Encrypt Devices and Information

Encryption helps protect information if a device is lost, stolen or accessed without permission.

Business laptops, desktops and mobile devices should use full-disk encryption.

Sensitive information should also be encrypted:

While stored
While being transmitted
When shared externally

Services such as Microsoft Purview sensitivity labels can help classify documents and apply protection based on their contents.

Protect Your Network

Business networks should be protected by properly configured security equipment.

This may include:

Next-generation firewalls
Secure wireless access points
Network segmentation
Web filtering
Intrusion prevention
DNS protection
VPN controls
Network monitoring

Guest Wi-Fi should be separated from the main business network.

Critical systems, such as servers, CCTV, phones and payment devices, may also need to be placed on separate network segments.

This limits the attacker’s ability to move across the network if one device is compromised.

Monitor Your Systems

Cyber attacks can remain undetected for days, weeks or even months.

Continuous monitoring helps identify unusual behaviour before it becomes a major incident.

Security monitoring may detect:

Suspicious logins
Unexpected administrator activity
Malware
Disabled security tools
Unusual data transfers
Mailbox forwarding rules
New accounts
Repeated login failures
Access from unknown locations
Changes to business systems

Alerts must also be reviewed and acted upon. Security tools are far less effective when nobody is monitoring them.

Train Your Employees

Employees are regularly targeted because criminals know that people can be easier to exploit than technology.

Cybersecurity awareness training should help staff recognise:

Phishing emails
Fake login pages
Payment fraud
Impersonation attempts
Malicious attachments
Suspicious links
Unexpected MFA prompts
Social engineering
Password risks
Public Wi-Fi dangers

Training should be practical, relevant and repeated regularly.

Phishing simulations can also help identify where additional training may be required.

The aim should not be to blame employees. It should be to help them make safer decisions and report mistakes quickly.

Create a Clear Reporting Process

Employees need to know what to do when something appears suspicious.

They should have a simple way to report:

Phishing emails
Lost devices
Unexpected login prompts
Suspicious payment requests
Malware warnings
Accidental data sharing
Unusual system behaviour

Early reporting can significantly reduce the impact of an incident.

Employees should never fear disciplinary action for reporting an honest mistake. Delayed reporting can make the situation much worse.

Prepare an Incident Response Plan

Every business should assume that a cybersecurity incident is possible.

An incident response plan explains what should happen when an attack occurs.

It should define:

Who leads the response
Who contacts the IT provider
How affected systems are isolated
How passwords are reset
How customers and suppliers are informed
When legal or regulatory advice is required
How evidence is preserved
How backups are restored
Who communicates with staff
How normal operations resume

The plan should be documented, accessible and tested.

During a real incident, there may not be time to decide these responsibilities from scratch.

Protect Against Payment Fraud

Cyber criminals frequently target payment processes.

They may compromise an email account, impersonate a director or alter bank details on an invoice.

Businesses should introduce clear payment controls, including:

Independent verification of bank detail changes
Dual approval for significant payments
Known contact numbers
Separation of duties
Written approval processes
Extra checks for urgent requests

Payment information should never be changed based solely on an email request.

Review Third-Party Suppliers

Your organisation may be secure, but your suppliers could still create risk.

Third parties may have access to:

Business systems
Customer data
Cloud applications
Shared files
Network equipment
Remote support tools

Businesses should review what access suppliers have and whether it is still necessary.

Supplier access should be protected with MFA, monitored and removed when no longer required.

Cybersecurity requirements should also be included in supplier agreements where appropriate.

Remove Unsupported Technology

Old systems and unsupported software can create serious security risks.

When a product reaches end of support, it may stop receiving security updates. Any newly discovered vulnerabilities may remain unpatched.

Businesses should identify:

Unsupported operating systems
Old servers
Legacy applications
Unmanaged devices
End-of-life firewalls
Outdated network equipment

A replacement or upgrade plan should be created before support ends.

Carry Out Vulnerability Assessments

A vulnerability assessment can identify known weaknesses in your systems and devices.

This may include:

Missing security updates
Open network ports
Weak configurations
Outdated applications
Insecure services
Exposed systems

Assessments should be repeated regularly because the threat landscape and business environment continually change.

Consider Penetration Testing

Penetration testing goes further than a standard vulnerability scan.

A qualified security professional attempts to exploit weaknesses in a controlled way, helping determine how an attacker might gain access and what the potential impact could be.

Penetration testing can be particularly valuable for:

Internet-facing systems
Web applications
Remote access services
Cloud environments
Networks handling sensitive information
Businesses with compliance requirements

The findings should be clearly prioritised so the most serious risks can be addressed first.

Work Towards Cyber Essentials

Cyber Essentials is a UK government-backed scheme designed to help organisations protect themselves against common cyber attacks.

The framework focuses on key areas including:

Firewalls
Secure configuration
Security updates
User access control
Malware protection

Certification can demonstrate that your business has taken important steps to improve cybersecurity.

Cyber Essentials Plus includes an independent technical assessment and provides greater assurance.

Do Not Treat Cybersecurity as a One-Off Project

Cybersecurity is an ongoing business process.

New employees join. Devices are replaced. Applications are introduced. Threats evolve. Permissions change. New vulnerabilities are discovered.

Security controls should therefore be reviewed regularly.

A good cybersecurity programme includes:

Regular risk assessments
Ongoing patching
Security monitoring
Employee training
Backup testing
Access reviews
Policy updates
Incident response testing
Vulnerability management

Cybersecurity should form part of normal business operations rather than only receiving attention after an incident.

What Should Your Business Prioritise First?

Businesses that are unsure where to begin should focus on a small number of high-impact improvements.

Start with:

Enable multi-factor authentication.
Protect all devices with managed endpoint security.
Apply security updates promptly.
Introduce reliable, monitored backups.
Review administrator access.
Improve email security.
Train employees.
Secure remote access.
Monitor suspicious activity.
Create an incident response plan.

These measures can significantly improve your resilience against common attacks.
