10 Best Proactive Ways to Prevent Data Breaches

14 April

Data breaches can cost companies millions and erode customer trust overnight. The best defence? Proactive prevention. Here are the top strategies to keep your data locked down and your business secure.

Implement Strong Access Controls
Limit access to sensitive data to only those who truly need it and review permissions regularly.
Encrypt Everything
Whether it’s data at rest or in transit, encryption ensures that even if data is stolen, it’s unreadable. Opt for stronger Quantum-safe encryption where possible and make sure encryption keys are stored securely.
Keep Software & Systems Updated
Outdated software is a threat actor’s best friend. Apply security patches and updates promptly across all systems to close known vulnerabilities.
Regular Security Training for Empowering Employees
Humans are often the weakest link. Conduct ongoing cyber security training to teach staff how to recognise phishing attacks, social engineering, and other threats.
Use Endpoint Protection Tools
Install reputable antivirus, anti-malware, and endpoint detection and response tools across all devices, especially in a remote or hybrid workforce setup.
Monitor and Audit Continuously
Set up real-time monitoring of network traffic, user behaviour, and system logs. Use SIEM (Security Information and Event Management) tools to detect unusual activity early.
Have a Strong Password Policy
Guidance from NCSC is for “long and strong” but with password rotation only when needed (e.g suspected compromise, or staff change).
Secure Cloud Configurations
Cloud misconfigurations are a top cause of breaches. Use tools to audit and harden cloud environments, and apply the principle of least privilege.
Create and Test an Incident Response Plan
Prepare for the worst. Your incident response plan should be clear, tested regularly, and include communication protocols, data recovery steps, and legal considerations.
Perform Regular Security Reviews and Threat Emulation
Our security review service is there to establish your organisations cyber-security maturity. By conducting staff interviews and performing network vulnerability scans, we can work out the right course for your organisation.
