The last time this page was updated, buying antivirus meant picking a boxed product that scanned files against a list of known viruses. That market is gone. In 2026, a business protects its computers with endpoint protection: software that watches behavior, blocks ransomware before it encrypts anything, and lets you see and respond to what is happening across every device from one console. The word antivirus stuck around, but what you are actually buying changed underneath it.
The roster changed too. Several names from the old top-10 list either merged into each other or left the US market entirely, and the products worth your money now are built for businesses, not for a single home PC. This guide covers the current picks, what they cost in 2026, and what happened to the tools you may remember.
Key takeaways
- Bitdefender GravityZone is the best value for most small businesses, at roughly $27 to $39 per device per year.
- Microsoft Defender for Business is the easy call if you already run Microsoft 365, at about $3 per user per month standalone.
- CrowdStrike Falcon Go ($59.99/device/year) and SentinelOne (from $69.99/device/year) are the cloud-native EDR options when you want top-tier detection and response.
- ESET remains a strong, light-footprint business pick, one of the few names from the old list still worth buying for a company.
- Kaspersky is off the table for US buyers. Its sale has been banned in the US since July 2024, and updates to US customers stopped in September 2024.
What changed since the old antivirus top 10
Three shifts matter before you compare products. First, protection moved from signatures to behavior. Modern threats, especially ransomware, often use files that have never been seen before, so matching against a known-virus list is not enough. Today’s business tools use next-generation antivirus (NGAV) plus endpoint detection and response (EDR), which watch what a program does and can roll back damage.
Second, the vendor list consolidated hard. AVG, Avast, Avira, and Norton are now all consumer brands under a single company, Gen Digital. McAfee’s enterprise business was spun off and is now Trellix. Webroot is owned by OpenText, and F-Secure split its business unit into a separate company, WithSecure. Four of the ten names on the old list effectively became one, and several others changed hands.
Third, Kaspersky left the US market. In June 2024 the US government banned the sale of Kaspersky software, with new sales prohibited from July 20, 2024 and software updates to US customers cut off on September 29, 2024. Whatever its technical merits, it is no longer a legal option for a US business, so it is not on this list.
The best business antivirus and endpoint protection in 2026
| Product | Best for | Type | Starting price (2026) |
|---|---|---|---|
| Bitdefender GravityZone | Best value for small business | NGAV + optional EDR | ~$27–39/device/yr |
| Microsoft Defender for Business | Microsoft 365 shops | NGAV + EDR | ~$3/user/mo |
| CrowdStrike Falcon Go | Cloud-native EDR, well-known | NGAV + EDR | $59.99/device/yr |
| SentinelOne Singularity | Autonomous detection + rollback | NGAV + EDR | from $69.99/device/yr |
| ESET PROTECT | Light footprint, older hardware | NGAV + optional EDR | ~$180/yr for 5 devices |
| Malwarebytes / ThreatDown | Remediation and simplicity | NGAV + optional EDR | ~$50/endpoint/yr |
Prices are US list rates as of July 2026. Endpoint pricing is usually billed per device (or per user) per year and drops with volume, so treat these as starting points and expect volume and multi-year discounts.
1. Bitdefender GravityZone: best value for most small businesses
Who it is for: Small and midsize businesses that want top-tier malware detection without enterprise pricing or a security team to run it. Bitdefender was number one on the old list and it is still one of the strongest engines you can buy, now packaged for business through GravityZone.
What you get: Behavior-based protection, ransomware mitigation with file rollback, web filtering, and a single cloud console to manage every device. EDR is available as an add-on when you are ready for detection and response features, so you can start simple and grow into it.
What it costs in 2026: GravityZone Business Security runs roughly $27 to $39 per device per year at list, with promotions often landing below that. For a ten-person shop, that is a few hundred dollars a year, which is the reason it wins on value.
Where it falls short: The console packs in a lot of options, which can feel dense at first, and the full EDR and extended detection features live in higher tiers that cost more. For pure prevention, the entry tier is plenty.
2. Microsoft Defender for Business: the built-in choice for Microsoft 365
Who it is for: Any business already paying for Microsoft 365. Defender for Business turns the protection built into Windows into a managed, business-grade product with a central console, and if you run Windows everywhere it is hard to argue against.
What you get: Next-generation antivirus, endpoint detection and response, automated investigation and remediation, and attack-surface reduction rules, all managed from the Microsoft security portal. It covers Windows, macOS, iOS, and Android.
What it costs in 2026: About $3 per user per month as a standalone product. It is also bundled into Microsoft 365 Business Premium at roughly $22 per user per month, so many businesses already own it without realizing it.
Where it falls short: The experience is best inside a Microsoft-centric setup, and getting the most out of the console assumes some comfort with Microsoft’s admin tools. Mixed or heavily Mac and Linux fleets may prefer a vendor-neutral option.
3. CrowdStrike Falcon Go: the best-known EDR, now sized for SMBs
Who it is for: Businesses that want the same cloud-native technology large enterprises use, in a package priced for a smaller fleet. Falcon Go is CrowdStrike’s small-business tier, capped at around 100 devices.
What you get: A lightweight agent, strong behavior-based prevention, and the detection-and-response pedigree CrowdStrike is known for. Because it is cloud-managed, there is no on-site server to maintain.
What it costs in 2026: Falcon Go lists at $59.99 per device per year. Higher tiers such as Falcon Pro and Enterprise add features and cost more (Falcon Enterprise runs around $184.99 per device per year), typically through a sales quote.
Where it falls short: It costs more per device than Bitdefender or Defender, the device cap on Go means fast-growing companies move to a quoted tier, and the deeper features assume someone will actually watch the alerts.
4. SentinelOne Singularity: autonomous response and rollback
Who it is for: Businesses that want EDR which can act on its own, including undoing ransomware damage automatically. SentinelOne competes directly with CrowdStrike and is frequently the other name on the shortlist.
What you get: On-device AI that detects and can automatically contain threats, one-click rollback of malicious changes on Windows, and a clean management console. The autonomous angle is genuinely useful for teams without a dedicated analyst.
What it costs in 2026: Singularity Core starts at $69.99 per device per year, Control at about $79.99, and Complete at $159.99 and up, depending on how much detection and response you need.
Where it falls short: Like CrowdStrike, it sits at the higher end of SMB pricing, and the more advanced tiers reward businesses that will use the response tooling rather than set it and forget it.
5. ESET PROTECT: light on the machine, still strong for business
Who it is for: Businesses running older or lower-powered hardware, or anyone who wants protection that stays out of the way. ESET was on the old list and is one of the few names there that still makes sense to buy for a company today.
What you get: A famously light agent, consistently high independent-lab scores, and a business console (ESET PROTECT) with optional EDR through ESET Inspect. It runs quietly without dragging down day-to-day performance.
What it costs in 2026: ESET Small Business Security runs roughly $180 to $410 per year for 5 to 20 devices, which works out to about $20 to $36 per device per year. Larger deployments move to a sales quote.
Where it falls short: ESET is deliberately conservative, so it is not the flashiest EDR on the market, and the more advanced response features require the higher tiers and add-ons.
6. Malwarebytes (ThreatDown): simple protection and cleanup
Who it is for: Small businesses that want straightforward protection with excellent remediation, without a heavy console. Malwarebytes built its reputation on cleaning up infections other tools missed, and its business line (now branded ThreatDown) carries that forward.
What you get: Next-generation antivirus, ransomware protection, and strong remediation, with optional EDR and managed detection tiers if you want them. The setup is quick and the console is easy to learn.
What it costs in 2026: Around $50 per endpoint per year for small deployments under about 20 devices, with EDR and managed tiers priced above that.
Where it falls short: The prevention engine, while good, does not top the independent charts the way Bitdefender or the big EDR vendors do, and larger organizations may want deeper reporting than the entry tier provides.
What happened to the rest of the old top 10
If you came here from the old version, here is where those names went. Norton, AVG, Avira, and Avast are all now consumer brands under Gen Digital, so choosing among them is really choosing packaging from one company; for a business, Norton Small Business is the relevant offering. McAfee’s enterprise arm became Trellix, while consumer McAfee continues separately. Webroot is now owned by OpenText and sold to businesses under that umbrella. F-Secure kept the consumer brand and spun its business products into a separate company, WithSecure. And Kaspersky, as noted, can no longer be sold to US customers. The takeaway for a buyer is simple: judge the current product and its owner, not the name you remember from a decade ago.
How to choose the right one for your business
You want the best protection for the money: Bitdefender GravityZone. Top-tier detection at small-business pricing, with EDR available when you need it.
You already run Microsoft 365: Microsoft Defender for Business. You may already own it through Business Premium, and it is well integrated with the tools your team uses.
You want enterprise-grade detection and response: CrowdStrike Falcon or SentinelOne. Both bring cloud-native EDR down to a size a smaller company can buy, at a higher per-device price.
You have older hardware or want minimal overhead: ESET PROTECT. A light agent with a long track record, still a sound business choice.
Frequently asked questions
Is antivirus still enough for a business in 2026?
Basic signature antivirus is not. Modern threats use files that have never been seen before, so a business needs next-generation antivirus plus endpoint detection and response, which watch behavior and can stop and reverse an attack. Every product in this guide provides that, either in the base plan or as an add-on.
Can my business still use Kaspersky?
Not in the US. The US government banned new sales of Kaspersky software from July 20, 2024, and cut off updates to US customers on September 29, 2024. Running an unpatched security product is a risk in itself, so US businesses should move to one of the alternatives here.
How much should a small business budget per device?
Plan on roughly $25 to $40 per device per year for strong prevention (Bitdefender, ESET), or about $3 per user per month if you go with Microsoft Defender for Business. Cloud-native EDR like CrowdStrike or SentinelOne runs $60 to $80 per device per year and up. Prices drop with volume and multi-year terms.
What is the difference between antivirus, NGAV, and EDR?
Traditional antivirus matches files against a list of known threats. Next-generation antivirus (NGAV) adds behavior analysis to catch unknown malware. Endpoint detection and response (EDR) records what happens on each device so you can investigate an incident and reverse the damage. Business tools now bundle these together.
Do free antivirus tools work for a company?
For a single home PC, maybe. For a business, no: free tools lack central management, reporting, and the response features you need when several machines are involved, and their licenses usually prohibit commercial use. The paid business tiers here exist for exactly that reason.
The verdict
For most small and midsize businesses, Bitdefender GravityZone gives you the strongest protection per dollar, and if you already pay for Microsoft 365, Microsoft Defender for Business is the practical default you may already own. When you want enterprise-grade detection and response and have someone to act on it, CrowdStrike Falcon or SentinelOne are the two to price out.
Whatever you choose, buy the business version with a central console, not a consumer app stretched across your office. Most vendors offer a free trial, so deploy your top two to a handful of machines and compare the console and the alerts before you roll out to everyone.
