​How Agentic AI Is Changing The Way MSPs Defend SMBs

Dor Eisner is the CEO & Co-Founder of Guardz, a company helping MSPs protect SMBs and build a safer digital world.

For years, small and midsize businesses (SMBs) relied on being too small to notice. That assumption is now dangerously outdated.

AI enables attackers to target thousands of organizations simultaneously, identify the weakest entry points and execute high-volume “spray and pray” campaigns. Threat data from my company illustrates the scale: We tracked over 14,000 unique spray IPs per month targeting multiple accounts simultaneously, growing 13% month over month.

More telling than the volume is the quality. AI-generated phishing campaigns are now contextually accurate and personalized using real email history from previously compromised accounts. Many of the obvious signs that once exposed phishing attempts have largely disappeared.

As attackers weaponize AI to increase speed and scale, managed service providers (MSPs) are turning to agentic AI to fight back. By combining advanced triage and analysis with autonomous response capabilities, they can deliver continuous, real-time detection and response for SMB customers at machine speed.​ ​

The question most MSP leaders ask is not whether agentic AI works but whether it can be trusted to operate safely on behalf of clients. That hesitation is legitimate, and it’s exactly what this article is designed to address: what agentic AI actually does and how MSPs can govern it responsibly.​

How Agentic AI Fits The SMB Security Gap

One of the main functions of MSPs is to provide access to enterprise-grade cybersecurity tools, along with the required specialized knowledge to manage them, for SMBs who find cybersecurity and high-level AI complex, costly and confusing. ​

Continuous And Autonomous

Keeping humans in control doesn’t mean keeping humans in the loop for every action. The key is that MSPs define the rules of engagement upfront, and within those boundaries, agentic AI can move at a speed no analyst team can match.
