I’ve been reading about how Ransomware-as-a-Service (RaaS) has made it incredibly easy for low-level hackers to launch sophisticated attacks against small businesses. As a business owner with limited IT staff, what are the most critical, cost-effective steps I can take right now to harden our perimeter? We already use a basic firewall, but I’m worried that isn't enough to stop modern credential harvesting or lateral movement if a breach occurs.

For a small business, the most impactful move you can make is implementing Multi-Factor Authentication (MFA) across every single entry point, especially for remote access. In a project I consulted on in early 2023, we found that 90% of attempted RaaS incursions were stopped at the login screen because the attackers couldn't bypass the second factor. Additionally, ensure you have an "immutable backup" strategy—meaning backups that cannot be deleted or encrypted even if your main admin account is compromised. This is your ultimate safety net if the worst happens.
Are you currently conducting regular phishing simulations for your staff, or is your focus primarily on the technical hardware side?
I'd suggest looking into an EDR (Endpoint Detection and Response) solution. It helps identify suspicious lateral movement that traditional antivirus software usually misses.
I agree with Brandon. EDR is much more proactive. It looks at behavior rather than just matching file signatures, which is how most RaaS variants hide.
That’s a vital point, Gregory. Human error is often the "initial access vector" for RaaS. Even the best firewall can't stop a staff member from clicking a malicious link. I recommend using a platform like KnowBe4 to train your team. It’s better to have them fail a fake test today than a real attack tomorrow. This builds a human firewall that complements your technical ones.
