Protecting Your Business from Ransomware Attacks
Ransomware doesn’t discriminate by company size. In our experience supporting businesses across Central Florida, small companies with 10-50 employees are actually hit more frequently than large enterprises because they’re easier targets. The attackers know these businesses often lack dedicated security teams and have weaker defenses. Learn more about our ransomware recovery services.
How Ransomware Gets Into Your Network
The entry point is almost always human. A phishing email with a malicious attachment, a compromised website that downloads malware, or stolen credentials from a previous data breach. Once inside, the ransomware spreads laterally through your network, encrypting files on every device and server it can reach.
Modern ransomware is patient. Some variants sit quietly in your network for weeks, mapping out your systems, identifying your backup locations, and waiting until they can cause maximum damage. By the time you see the ransom note, the attackers have already been inside for days or weeks.
Prevention: The Layers That Matter
No single tool stops ransomware. You need layers of defense, each one catching what the others miss:
Email filtering catches the majority of phishing attempts before they reach your inbox. Business-grade email security goes beyond basic spam filtering to analyze attachments in sandboxes and check links in real time.
Endpoint Detection and Response (EDR) replaces traditional antivirus with behavioral analysis. Instead of just matching known virus signatures, EDR watches for suspicious behavior like rapid file encryption and stops it immediately.
Network segmentation limits how far ransomware can spread. If your accounting system is on a separate network segment from your general workstations, ransomware on an employee’s computer can’t reach your financial data.
Patching closes the vulnerabilities that ransomware exploits. The WannaCry attack in 2017 spread through a Windows vulnerability that Microsoft had patched two months earlier. Every unpatched system was hit. Every patched system was fine.
Your Backup Is Your Last Line of Defense
If ransomware gets through your prevention layers, your backup is what saves you from paying the ransom. But only if your backup was set up correctly.
Follow the 3-2-1 rule: three copies of your data, on two different types of media, with one copy stored offsite or in an immutable cloud backup that ransomware can’t encrypt. Test your restores quarterly. We’ve seen businesses discover their backups had been silently failing for months only when they needed them most.
If You Get Hit: The First 30 Minutes
Disconnect affected devices from the network immediately. Don’t turn them off, just unplug the network cable or disable Wi-Fi. Turning them off can destroy forensic evidence. Contact your IT provider and your cyber insurance carrier. Do not communicate with the attackers directly, and do not pay the ransom without professional guidance. Report the incident to the FBI’s Internet Crime Complaint Center at ic3.gov.
The businesses that recover fastest are the ones that had an incident response plan before the attack happened. Having your IT provider’s emergency number, your insurance policy details, and your backup recovery procedures documented and accessible offline makes the difference between a bad day and a business-ending event.

Frequently Asked Questions
What should I do if my business gets hit by ransomware?
Immediately disconnect affected devices from the network to prevent spread. Do not pay the ransom, as there is no guarantee of data recovery. Contact your IT provider, file a report with the FBI (ic3.gov), and restore from clean backups. If you have cyber insurance, contact your provider immediately.
Can ransomware be removed without paying?
In many cases, yes. If you have clean, recent backups stored offline or in the cloud, you can wipe affected systems and restore your data. Some ransomware variants also have free decryption tools available through the No More Ransom project (nomoreransom.org).
How do I prevent ransomware attacks?
Maintain current backups stored separately from your network, keep all software updated, train employees to recognize phishing emails, use endpoint detection and response (EDR) software, segment your network, and restrict administrative privileges to only those who need them.
