5 Smart Data Security Tips For Businesses

Cyberattackers aren’t just targeting tech giants anymore – small and mid-sized businesses are increasingly in the firing line. From ransomware to AI-based phishing scams, criminals are getting more sophisticated, and the cost of a breach can even pull a company under. A resilient data security strategy is now a business survival issue. Here are five security essentials that will protect your company’s data, reputation, and bottom line – and help you stay ahead of cybercriminals in 2025.

Lock down data with encryption and backup immutability

Encrypting your sensitive files (while stored and while in transit) means that even if the unthinkable happens and attackers gain access, they won’t be able to easily read or use your data. Pair encryption with immutable backups (hardware enforced or cloud-based write once systems), which can’t be altered or deleted for a set period, to shield the business against ransomware and insider threats to data. Whether using local devices or business cloud storage, make sure your backup system is both secure and routinely tested.

Track shadow IT and limit access with zero-trust controls

A zero-trust model assumes that no user or device (even one issued by the company) should be trusted by default. Combine least-privilege permissions with multi-factor authentication to limit potential damage if any staff credentials do end up being hacked. You also need to tackle hidden software use in your business by identifying and managing any unauthorized apps or cloud services (‘shadow IT’) that employees might be using and that haven’t been audited or checked for vulnerabilities.

Plan for upcoming quantum computing challenges

Your security plan must also think beyond today’s risks and consider the impact of quantum computing, which could one day render the encryption methods that you use obsolete. If your business will be storing sensitive data for years then you should begin exploring post-quantum cryptography to stay ahead.

Pursue CISA’s Cyber Essentials and stay ahead of new regulations

If you’re looking for a reliable starting point, The Cybersecurity and Infrastructure Security Agency’s (CISA) Cyber Essentials provide a straightforward foundation for security readiness. It’s also wise to monitor changes in cybersecurity laws, as future regulations may expand reporting requirements and introduce new penalties.

Test your response plan and leverage government resources

You might have the most well thought out incident response plan, but it’s only useful if it will work in the real world. Schedule regular drills so your team knows exactly what to do in a crisis. If cybersecurity will be a financial burden on your business, look into initiatives like the SBA’s Cybersecurity for Small Business Pilot Program, which offers grants, resources, and training to help small businesses strengthen their defenses.

Staying cybersecure is an ongoing process

Cybersecurity isn’t a one-time project, but a constant process of improvement. By combining encryption, zero-trust principles, forward-thinking strategies, and well-rehearsed response plans, businesses can significantly reduce their exposure to risk.
