Ransomware isn’t new, but it’s evolved and fast. What used to be a problem mainly for large corporations now targets small businesses, remote teams, and individuals. In 2025, no one is off-limits.

You don’t need to panic, but you do need a plan. When ransomware locks you out of your files, it can mean lost work, downtime, and sometimes permanent damage. The good news? With the right cybersecurity best practices and tools, most attacks can be prevented or contained.

Let’s break down how ransomware works and what you can do to protect yourself.

At its core, ransomware is malicious software (malware) designed for cyber extortion. It encrypts your data, locking you out until you pay a ransom, usually in cryptocurrency. In some cases, attackers also threaten to leak your sensitive files online if you refuse to pay.

Ransomware infections typically enter your system through common cybercriminal tactics like:

• Phishing emails that appear legitimate
• Clicking malicious links or opening infected attachments
• Exploiting unsecured remote access tools like Remote Desktop Protocol (RDP)
• Taking advantage of unpatched software vulnerabilities

One minute your system is fine. The next, your screen displays a ransom note demanding payment.

Ransomware Protection Tips That Actually Work: Proven Cybersecurity Strategies

Stopping ransomware requires a layered approach. No single tool is foolproof, but combining these cybersecurity best practices significantly reduces your risk.

1. Back Up Your Data to Protect Against Ransomware Attacks

A strong data backup strategy is your best insurance policy. If an attack happens, having clean, up-to-date backups means you can restore your system without paying the ransom.

Here’s what you need to do:

• Back up data regularly and automatically
• Keep at least one backup offline or in a secure cloud environment (offline backup solution)
• Test backups frequently to ensure they can be restored successfully

Don’t risk losing data before realizing your backup isn’t working—you can certainly prevent this problem!

2. Update Software and Operating Systems Regularly to Close Security Gaps

One of the most common cybersecurity vulnerabilities comes from outdated software. Cybercriminals exploit these known flaws to launch attacks.

Make it a habit to:

• Enable automatic updates on your operating system, browsers, and apps
• Regularly patch plugins and third-party software
• Update all endpoints, including mobile devices and tablets

Updates aren’t exciting, but they’re essential for ransomware prevention.

3. Use Ransomware Detection and Antivirus Tools with Real-Time Protection

Antivirus software today does more than scan for known threats-it detects suspicious behaviors that could signal a ransomware attack.

Look for security solutions that offer:

• Real-time monitoring and ransomware protection built in
• Automatic updates and threat alerts
• Endpoint security across all your devices

Install and keep these tools active to stop ransomware before it encrypts your files.

4. Avoid Phishing and Suspicious Links to Prevent Ransomware Delivery

Email phishing remains the most common ransomware delivery method.

Be vigilant about:

• Emails claiming urgent action like “invoice ready” or “account suspended”
• Links that look similar but are slightly off from legitimate domains
• Unexpected attachments or downloads

If something feels off, don’t click-verify the sender through another channel.

5. Disable Unused Features and Lock Down Access Points to Reduce Vulnerabilities

Features like Remote Desktop Protocol (RDP) and Microsoft Office macros are often exploited in attacks.

If you don’t need these features:

• Disable them to close common ransomware entry points
• Regularly review and restrict admin and user permissions
• Turn off public-facing services that aren’t actively used

Tightening access controls lowers your ransomware risk.

Real-world example: In mid-2025, SonicWall warned of ransomware attacks targeting its Gen 7 firewalls with SSLVPN enabled. Hackers used stolen VPN credentials to get into networks, sometimes deploying Akira ransomware within hours. SonicWall advises updating to SonicOS 7.3.0, resetting all VPN passwords, turning on MFA, and disabling SSLVPN if you don’t need it.

6. Use Strong Passwords and Two-Factor Authentication to Block Unauthorized Access

Weak or reused passwords are a top cause of ransomware breaches.

Protect your accounts by:

• Creating long, unique passwords for each account
• Enabling multi-factor authentication or two-factor authentication on email, cloud storage, VPNs, and admin accounts

Even if attackers steal your password, multi-factor authentication can stop them from gaining access.

7. Train Your Team on Cybersecurity Best Practices to Prevent Human Error

Human error remains a leading cause of ransomware incidents.

Whether in a business or at home, everyone who uses your network should:

• Understand how to spot phishing and social engineering scams
• Know when and how to report suspicious activity quickly
• Follow safe browsing and email habits

A security-aware team is your first line of defense.

What Not to Do During a Ransomware Attack

Even with precautions, if ransomware strikes, avoid these common mistakes:

• Don’t pay the ransom. It doesn’t guarantee data recovery and encourages more cyberattacks.
• Don’t delay action. Early detection and response make recovery easier.
• Don’t skip updates or neglect to back up. Outdated systems and missing backups increase damage risk.

Building a Ransomware Prevention Plan That Works

Ransomware won’t disappear anytime soon, but you don’t have to be a cybersecurity expert to protect yourself. By setting up solid ransomware protection measures, keeping software updated, and staying vigilant, you can dramatically reduce your risk.

It’s about building good habits and using proven cybersecurity strategies to stay safe.
