How to Improve Cyber Security for Your Business in Sussex
Cyber threats are on the rise, and small to medium-sized businesses across Sussex are increasingly being targeted. From phishing scams to ransomware attacks, it’s more important than ever to protect your data, your staff, and your reputation. This guide outlines practical steps you can take to improve cyber security for your business in Sussex — whether you’re in Brighton, Worthing, Chichester, or anywhere in between.
1. Conduct a Cyber Security Audit
Start by assessing your current security posture. A cyber security audit helps you identify vulnerabilities in your systems, networks, and policies.
What to include in your audit:
- User access and permissions
- Antivirus and endpoint protection
- Patch management and software updates
- Backup and disaster recovery processes
- Firewall and network security settings
You can carry this out internally or partner with a local IT provider like Cyber United to perform a professional audit.
2. Enable Multi-Factor Authentication (MFA)
MFA adds a critical layer of protection by requiring a second form of verification before access is granted. This significantly reduces the risk of account compromise due to stolen or weak passwords.
Where to implement MFA:
- Microsoft 365 and Google Workspace
- Remote desktop access
- VPN connections
- Any critical business application
3. Train Your Team on Cyber Threats
Human error is one of the most common causes of cyber incidents. Providing regular training helps your staff recognise and avoid common threats.
Topics to cover:
- How to spot phishing emails
- Safe internet and email usage
- Creating strong passwords
- Reporting suspicious activity
4. Keep Systems and Software Up to Date
Outdated software is a major vulnerability. Hackers often exploit known flaws in unpatched systems.
Best practices:
- Enable automatic updates where possible
- Regularly check for firmware updates on firewalls and routers
- Use a patch management system to track and deploy updates
5. Use a Professional Antivirus and Endpoint Protection Solution
Basic antivirus isn’t enough anymore. Modern cyber threats require advanced tools such as Endpoint Detection and Response (EDR).
Features to look for:
- Real-time threat detection
- Behaviour-based malware identification
- Ransomware rollback and recovery
At Cyber United, we offer managed antivirus and EDR as part of our support packages.
6. Back Up Your Data — Regularly
Relying on cloud platforms like Microsoft 365 or Google Drive doesn’t mean your data is backed up properly. Always maintain a separate backup solution.
What to back up:
- Emails
- OneDrive, SharePoint, and Teams data
- Local files and databases
Backup tips:
- Follow the 3-2-1 rule (three copies, two media types, one offsite)
- Test recovery procedures regularly
7. Secure Your Wi-Fi and Network Infrastructure
A poorly secured network can give attackers easy access to your systems.
Steps to take:
- Change default router passwords
- Use strong encryption (WPA3 where available)
- Hide your SSID and limit guest access
- Segment your network for staff, guests, and devices
8. Implement User Access Controls
Not everyone needs access to everything. Limiting user access minimises the damage that can be caused by a compromised account.
Recommendations:
- Apply the principle of least privilege
- Use role-based access controls
- Regularly review permissions and remove access for former staff
9. Protect Email and Stop Phishing
Email is the number one vector for cyber attacks. Protect your communications with the right tools and protocols.
Key steps:
- Set up SPF, DKIM, and DMARC to prevent spoofing
- Use email filtering tools to detect spam and malware
- Enable Safe Links and Safe Attachments in Microsoft 365
10. Work with a Local Cyber Security Expert
Businesses across Sussex can benefit from partnering with a local IT and cyber security provider who understands the region’s needs.
Why go local:
- Faster onsite response in Brighton, Lewes, Eastbourne, and beyond
- Personalised service from people who know your industry
- Ongoing support with no call centres or confusing jargon
At Cyber United, we help Sussex-based businesses stay secure, compliant, and one step ahead of cyber threats.
