Every business needs solid endpoint protection. If you’re working with a managed service provider, they likely already manage an antivirus solution on your behalf. But as the owner of an IT company, I wanted to take a fresh look at what’s actually out there — so I dug into the history and current state of the major players. Here’s what I found.

Norton Small Business

Rating: ★★★☆☆

Dating back to 1990, Symantec’s Norton Antivirus was a household name and an early pioneer of heuristic detection — the ability to stop virus variants before they could spread. For a long time, that reputation carried the brand. In recent years, Norton has rebuilt the product from the ground up, but some of the same old patterns are already reappearing.

Pros: Decent detection; reasonable event handling.

Cons: Noticeable performance impact on endpoints; no centralized dashboard; overpriced for what you get.

Malwarebytes

Rating: ★★★★☆

In 2004, a Polish immigrant named Marcin Kleczynski got his family computer infected and couldn’t get Norton or McAfee to remove it. After three days of manual removal, he started building Malwarebytes. From its earliest version, it was clearly better than the legacy players at the time — and remarkably lightweight. For nearly 15 years it was the go-to recommendation for individual computers.

Today, Malwarebytes has scaled to serve larger organizations. Its quality remains good, though the pace of improvement has slowed. Some newer add-ons (like “delete your personal data from the internet”) feel gimmicky. It’s still a solid product — especially for endpoints where performance matters — but it’s showing its age in enterprise environments.

Pros: Fairly priced; lightweight; good detection; clean event handling.

Cons: No centralized management dashboard; browser extension is mostly ineffective; not built for server environments.

Webroot Endpoint Protection

Rating: ★★★☆☆

Founded in 1997, Webroot started with a narrow focus on spyware before expanding into a full enterprise suite marketed toward MSPs and IT teams. After its acquisition by Carbonite in 2019, expectations were low — but the product has held up reasonably well. The enterprise dashboard is functional if not pretty. Detection performance is adequate.

Pros: Good event handling; well-priced; solid enterprise dashboard.

Cons: Detection is mediocre; higher-than-average false positive rate; somewhat resource-intensive.

Trend Micro Small Business

Rating: ★★★☆☆

Trend Micro has a long history in server-side security, and you can feel that heritage in their endpoint product. It works, but it has always felt like a server security product adapted for workstations — with the resource consumption that implies. Good detection, but the performance overhead and lack of an enterprise dashboard make it harder to recommend over newer options.

Pros: Good detection; solid event handling.

Cons: Heavy on hardware resources; no enterprise dashboard; overpriced relative to performance.

ESET Protect Enterprise

Rating: ★★★☆☆

ESET NOD32 has an interesting history — founded under Soviet-era Czechoslovakia, where private entrepreneurship was technically banned. The founders registered ESET as a private company as soon as the USSR fell, and spent the following decades building traction in international markets.

ESET is relatively lightweight and effective at catching serious threats. Teams licensing is fairly priced and manageable. The concern is its detection methodology: ESET appears to rely on a more traditional heuristics model where threat definitions require manual updates from their team, which raises questions about zero-day detection speed. There are also geopolitical considerations worth noting for any software with Eastern European roots in the current environment.

Pros: Lightweight; good event handling; fairly priced.

Cons: Mediocre detection for newer threats; no enterprise dashboard.

SentinelOne

Rating: ★★★★★

SentinelOne entered the market in 2013 and went public on the NYSE in 2021, raising $1.2 billion. Not only have they built a polished interface and a feature-rich management backend, but they are pioneering AI-driven heuristic analysis — the ability to detect novel threats without relying on pre-built definition files.

The result is a product that stays ahead of new malware rather than catching up to it. Detection performance is excellent. The endpoint agent is one of the lightest in this list. The only real criticism is event handling — occasionally SentinelOne gets stuck in a quarantine loop that generates continuous notifications until the detection is manually resolved. The detected process is non-functional during that loop, so there’s no actual security risk — it’s an annoyance, not a gap.

Pros: Very lightweight; excellent detection; great enterprise dashboard.

Cons: Premium pricing (worth it); occasional quarantine notification loops.

The Verdict

In the AI era, it shouldn’t surprise anyone that AI-driven heuristic analysis is becoming the new standard for endpoint protection. SentinelOne has a head start on that transition and a polished product to show for it.

For Key MSP clients, we deploy SentinelOne as our standard endpoint protection platform. It’s the best option available today, and we’re confident it will continue to improve as AI capabilities advance.
