Ransomware protection for small business starts with a hard truth: backups alone will not save you. The FBI, CISA, and the FBI’s InfraGard partnership have all issued fresh warnings this year that ransomware groups are deliberately hunting companies with lean IT teams and no incident response plan. If that description fits your business, the warning is meant for you.
Key Takeaways
- Ransomware or extortion showed up in 88% of breaches at small and midsize businesses in 2025, compared to 39% at large organizations.
- The FBI, CISA, and international partners issued a joint advisory this year on a ransomware-as-a-service operation built to recruit affiliates and target under-resourced IT teams.
- Backups do not stop ransomware on their own; attackers now steal data and target backup systems before they ever encrypt a file.
- Managed cybersecurity services close the monitoring, patching, and response gaps that a lean in-house team cannot cover alone.

Why the FBI and InfraGard Are Watching Ransomware More Closely
InfraGard is the FBI’s information-sharing partnership with the private industry. It connects business owners and IT leaders directly to federal threat intelligence, instead of leaving them to piece it together from headlines after an attack has spread. The bureau built it so business leaders hear about emerging threats early enough to act on them.
That is exactly what happened in August 2026. The FBI, CISA, the Department of Defense Cyber Crime Center, the NSA, and the U.S. Secret Service released a joint advisory on Gunra, a ransomware-as-a-service operation (often shortened to RaaS).
In RaaS, the criminals who build the ransomware and the criminals who deploy it are often different people. So, developers rent out their malware to affiliates, who keep a cut of whatever ransom gets paid. That division of labor is why ransomware keeps getting easier to run and harder to trace.
It’s also why a group like Gunra can scale an attack campaign about as fast as a legitimate software company scales a product launch.
Why Small Businesses Are the Preferred Ransomware Target
Attackers target small businesses because the math favors them. Ransomware or extortion appeared in 88% of breaches at small and midmarket businesses, compared to 39% at large organizations. Large enterprises have security operations centers (SOCs) watching traffic around the clock. Most small businesses have an IT generalist juggling a ton of tasks like help desk tickets, projects, cybersecurity…and attackers know it.
And it’s important to mention that the tools attackers abuse often belong to the business itself. Attacks that use this approach are called, Living off the Land (LOTL) attacks.
Microsoft’s 2025 Digital Defense Report found that 79% of ransomware cases its incident responders investigated involved at least one remote monitoring and management (RMM) tool. That is the same software an IT team or provider uses to check on and fix computers without a truck roll.
When that access is not tightly locked down and watched, an attacker who steals one login can move laterally through an entire client environment using software that the business trusts.
What You Should Do in The First 24 Hours of a Ransomware Attack
The first 24 hours after discovering ransomware determine how much of the damage is reversible. Move through these steps in order, one at a time.
1. Isolate affected devices from the network immediately.
Unplug the cable or disable Wi-Fi rather than shutting the machine down, since a shutdown can wipe evidence investigators need.
2. Do not pay the ransom and do not wipe anything.
Paying does not guarantee a working decryption key, and wiping systems can destroy the evidence needed to understand how the attacker got in.
3. Call your managed IT or incident response provider before doing anything else technical.
Acting alone under pressure is how backups can get overwritten, or how logs get lost.
4. Report the incident to the FBI through the Internet Crime Complaint Center and to CISA.
Federal reporting to the Internet Crime Complaint Center helps investigators track the group behind the attack and can surface a decryption tool if one already exists.
5. Restore from a backup you have already tested.
A backup nobody has test-restored in the last year is a hope, not a plan.
What Ransomware Protection Requires in SMBs
Real ransomware protection for small business is layered. No single tool stops every attack, so the goal is to make an intrusion harder to start, harder to spread, and easier to recover from. These seven controls matter most for a lean IT team.
1. Multi-factor authentication (MFA) on every account (not just email).
MFA asks for a second proof of identity beyond a password, such as a code on a phone, so a stolen password alone cannot get an attacker in.
2. Software updates and patch management (on a fixed schedule).
Most ransomware does not need a clever trick to get in; it can enter your network through a known software flaw that a vendor published a fix for months earlier.
3. Employee phishing training that runs once a month (preferably with simulated phishing tests).
Most ransomware infections start with someone clicking a convincing email, and one annual training video will not change that habit.
4. Network segmentation.
This ensures that one infected laptop cannot reach every single server and document management system on the network in a single hop.
5. Immutable, offline-tested backups that are stored separately from the main network.
You want this because attackers are looking for and deleting/encrypting backups before they touch anything else. Their actions ensure that you’re “held hostage” in the situation.
6. 24/7 monitoring and detection (in addition to antivirus).
Antivirus catches known malware; monitoring, on the other hand, catches the unusual behavior that shows up before the ransomware payload runs.
7. A written incident response that has been practiced.
This step is important because it ensures that the first hour of an attack is spent executing steps instead of arguing/stressing about what to do next.

Small businesses are being hit harder than ever by ransomware attacks. This guide gives you a clear, actionable strategy to reduce risk and improve cyber resilience.
How Do Managed Cybersecurity Services Protect Small Businesses from Ransomware?
Managed cybersecurity services protect small businesses from ransomware by combining continuous monitoring, patch management, phishing-resistant authentication, and tested backup recovery into one coordinated program.
That means an intrusion will get caught and contained in minutes instead of it being discovered days (or weeks or months) later when your files are already encrypted.
A managed security provider, like Teal, will provide you with your own security operations center. They will watch for the small anomalies a basic antivirus program will not catch, like:
- An employee account logging in from two countries within the same hour
- A server suddenly talking to an unfamiliar IP address
- A scheduled backup that stopped running last Tuesday
Catching signals like those early is often the difference between a contained incident and recovery costs that end up in the six figures.
Ransomware Protection for Small Business Starts Before the Next Advisory
The FBI’s InfraGard warnings and CISA’s #StopRansomware guidance both warn that waiting for an attack to reveal your gaps is the most expensive way to find them. Ransomware protection works best as a standing program built around a comprehensive, defense-in-depth strategy.
