Bitdefender sells its business protection, GravityZone, online in three plans for 5 to 100 devices: Small Business Security, Business Security and Business Security Premium [1]. On Bitdefender's US compare page, one year for 5 devices showed $118.99, $132.99 and $311.49, each marked "30% OFF" a higher list price [1]. In AV-Comparatives' March to June 2026 business test, GravityZone Business Security Premium scored 99.8% in real-world protection, but it ranked 11th of 16 on performance impact [2]. For most small teams it is a strong, fairly priced choice if you budget for add-ons and renewal.

How we chose
This is a desk review, not a hands-on test: we did not install GravityZone. It is based on Bitdefender's product and compare pages, published reports from AV-Comparatives, AV-TEST and SE Labs, and the product pages of four alternatives small businesses often shortlist: Microsoft Defender for Business, ESET PROTECT, Sophos Endpoint and CrowdStrike Falcon Go. Pages were checked on 2026-11-08; prices are the US prices shown that day, before tax.

Bitdefender review: what the independent labs found
AV-Comparatives, March to June 2026. The lab tested "Bitdefender GravityZone Business Security Premium" on Windows 11 alongside products from Microsoft, ESET, Sophos and CrowdStrike [2]. In the Real-World Protection Test, Bitdefender blocked 399 cases and was compromised once, for a 99.8% protection rate with four false alarms, the highest rate among the five vendors in this review [2]. In the Malware Protection Test it scored 99.5% [2]. Performance was the weak spot: Bitdefender placed 11th of 16 in the lab's performance summary with an impact score of 26.3, against 3.7 for first-placed ESET [2]. It still earned the lab's "Approved" business product award for July 2026 [2].
The lab warns that readers "should not assume that the test results for one product in a vendor's business range will necessarily be the same for another product from the same vendor" [2].
AV-TEST. On AV-TEST's scale of up to 6 points each for protection, performance and usability [7], Bitdefender's latest business Windows entry, Business Security Enterprise 7.9 in December 2025, scored 6, 5.5 and 6 [8]. Enterprise is not one of the plans reviewed here.
SE Labs. SE Labs' April to June 2026 SMB endpoint report includes a factsheet for "BitDefender Small Office Security" rather than a GravityZone plan [9]. Because that is a different product, we did not use its results.
Bitdefender GravityZone — three plans for 5 to 100 devices
Bitdefender GravityZone is sold online in three stacked plans, each including everything in the tier below [1]. Online orders run from 5 to 100 devices, with a separate route for larger purchases [1].
Verified features: Small Business Security covers "protection against phishing, ransomware and web-based attacks," a security overview of all protected endpoints and visibility over detected threats [1]. Business Security adds Network Attack Defense, Web Access Control, Device Control and Endpoint Risk Analytics [1]. Business Security Premium adds HyperDetect tunable machine learning, a cloud-hosted Sandbox Analyzer and Microsoft Exchange coverage [1]. For the management console, Business Security offers "the choice of cloud or on-premise management" [10]. Bitdefender lists macOS, iOS, Linux and Windows as covered, says "Linux OSs are considered servers," and notes that the price covers desktops and laptops "and up to 30% file servers" [1].
Pricing: For one year at 5 devices, the compare page showed Small Business Security at $118.99, Business Security at $132.99 and Premium at $311.49, discounted from "Old Price" figures of $169.99, $189.99 and $444.99 [1]. At 10 devices it showed $227.49, $269.49 and $615.99 [1]. Patch Management, Full Disk Encryption, Security for Mobile and Security for Email are add-ons purchased separately [1]. Premium can be tried first with a "1-month Free Trial" [11].
Strengths: Protection is the main reason to buy: Bitdefender's 99.8% real-world result was the highest of the five vendors here in the same AV-Comparatives round [2]. At the discounted prices, the step from Small Business Security to Business Security costs $14 a year at 5 devices [1] and adds device control and network attack defense, which is where most small teams should land. The on-premises console option [10] suits businesses that want security data on their own servers.
Limitations: The online prices are discounts from an "Old Price," and subscriptions "will automatically renew" unless you cancel that option [1], so ask what year two costs. Performance impact was middling [2]. Security for Mobile, patching and disk encryption cost extra [1], while some rivals bundle at least one of them. The lab results come from Premium and Enterprise, not the two cheaper plans [2, 8].
Best fit: Businesses with 5 to 100 Windows and Mac computers, no security staff, and a priority on protection over raw speed. Start with Business Security; choose Premium if you run Exchange on-site or want sandbox analysis.
Microsoft Defender for Business — the default for Microsoft 365 shops
Microsoft Defender for Business is Microsoft's endpoint security product for smaller companies, sold "on its own or as part of Microsoft 365 plan" [3].
Verified features: It covers "up to 300 users and up to five devices per user," protects Windows, macOS, iOS and Android, and includes vulnerability management, next-generation antivirus and "AI-powered endpoint detection and response (EDR) with automatic attack disruption" [3]. Microsoft 365 Business Premium includes Defender for Business plus Intune Plan 1 [3].
Pricing: $3.00 per user per month, paid yearly [3]. Servers need the separate Defender for Business servers add-on [3].
Strengths: Per-user pricing covering several devices per person suits teams with a laptop and phone each, and EDR is in the base product [3]. In the same AV-Comparatives round, Microsoft's tested product, Defender Antivirus with MEM, scored 98.8% in real-world protection with zero false alarms [2].
Limitations: Bitdefender's real-world rate was higher, 99.8% against 98.8% [2]. The product is capped at 300 users and servers cost extra [3], whereas Bitdefender's price includes a share of file servers [1].
Best fit: Companies under 300 people on Microsoft 365, especially Business Premium customers who may already own it.
ESET PROTECT — the lightest footprint in the lab results
ESET PROTECT is ESET's business platform, sold in tiers that start with Core [4].
Verified features: Core includes "next-gen antivirus for computers, servers, mobiles and cloud VMs," firewall, web and device control, and "quantum-ready encryption" [4].
Pricing: ESET's US plans page showed Core at $549.00 for 10 devices on a one-year term [4].
Strengths: The lab-tested ESET PROTECT Entry placed first in AV-Comparatives' performance summary with an impact score of 3.7 [2]. Encryption and mobile coverage are part of Core [4], while Bitdefender sells both as add-ons [1].
Limitations: At 10 devices, Core costs more than Bitdefender Business Security at either its $269.49 discounted or $384.99 list price [4, 1]. ESET's real-world protection rate in the same round was 98.8% with two false alarms, below Bitdefender's 99.8% [2].
Best fit: Offices with older or lower-powered PCs, or teams that want encryption included rather than bolted on.
Sophos Endpoint — prevention-first, but quote-only
Sophos Endpoint is Sophos's endpoint protection product, described as "a unified endpoint protection and EDR solution" [12].
Verified features: Sophos says it combines "AI-powered prevention, 60+ exploit mitigations enabled by default, CryptoGuard ransomware rollback, and built-in detection and response in a single lightweight agent for Windows, macOS, and Linux" [12].
Pricing: Sophos does not publish prices on the product page. You request a quote, and Sophos describes "simple, per-user pricing with no hidden extras" [5].
Strengths: Detection and response is built into the base product [12]. Sophos says protection is "enabled by default" so SMBs "without a dedicated security team" need no tuning [12].
Limitations: With no public price, you cannot compare costs without talking to sales [5]. In AV-Comparatives' H1 2026 test, Sophos Intercept X Advanced scored 98.3% in real-world protection, placed 16th of 16 on performance impact and was "NOT APPROVED" [2].
Best fit: Businesses that buy through an IT provider and are comfortable with a custom quote.
CrowdStrike Falcon Go — per-device antivirus with monthly billing
CrowdStrike Falcon Go is CrowdStrike's "Security Essentials" bundle for small businesses [6].
Verified features: Falcon Go includes Next-Gen Antivirus, Device Control for USB devices, Mobile Device Protection for Android and iOS, and Express Support [6].
Pricing: $59.99 per device billed annually, or $7.99 per device billed monthly, with purchases limited to a maximum of 100 devices [6].
Strengths: Monthly billing is useful for teams that change size often, and mobile protection is included in the base bundle [6].
Limitations: At 5 devices, a year of Falcon Go costs $299.95, more than double Bitdefender Business Security's $132.99 discounted price [6, 1]. AV-Comparatives tested Falcon Enterprise, not Go; it scored 98.5% in real-world protection with eight false alarms [2].
Best fit: Very small teams that value month-to-month terms over the lowest price.
How to choose a business antivirus plan
Start by counting what you need to protect the way each vendor counts it. Bitdefender prices by device and treats Linux machines as servers, with file servers capped at 30% of the license [1]. Software teams, such as a startup midway through SaaS development, often run Linux workstations, so check how those count. Microsoft prices per user with up to five devices each [3], and CrowdStrike prices per device [6].
Then decide how much response capability you need. If you want detection and response from day one, Microsoft and Sophos include it in their base products [3, 12].
Price the extras before comparing sticker prices: with Bitdefender, mobile security, patching and full disk encryption are separate purchases [1]. Ask every vendor what year two costs. Finally, read the lab report for the exact product you will buy, not just the brand, and trial it on a few real machines before a full rollout.
FAQ
Is Bitdefender legit for business use?
Yes. Bitdefender GravityZone Business Security Premium earned AV-Comparatives' "Approved" business product award in July 2026 after scoring 99.8% in its real-world protection test [2]. On AV-TEST, Bitdefender Business Security Enterprise 7.9 scored 6 for protection, 5.5 for performance and 6 for usability in December 2025 [8].
Is Bitdefender worth it for a small business?
For most teams of 5 to 100 devices, yes. Business Security cost $132.99 for 5 devices for one year when we checked, discounted from $189.99 [1], and Bitdefender posted the highest real-world protection rate of the five vendors here in AV-Comparatives' latest round [2]. The trade-offs are a middling performance score [2] and paid add-ons for mobile, patching and encryption [1].
What is Bitdefender GravityZone?
GravityZone is Bitdefender's business security line; its small-business packages are Small Business Security, Business Security and Business Security Premium [1]. Business Security runs on a unified platform with "the choice of cloud or on-premise management" [10].
What does Bitdefender Small Business Security include?
Protection against phishing, ransomware and web-based attacks, a security overview of protected endpoints, and visibility over detected threats [1]. Network Attack Defense, Web Access Control and Device Control need the Business Security tier; patching, encryption, mobile and email security are sold separately [1].
Our recommendation
For a small business that wants a dedicated endpoint product, Bitdefender GravityZone Business Security is the plan to start with: it pairs the strongest protection result among the vendors here [2] with a low entry price [1], and Premium is there if you need sandboxing. If your company already pays for Microsoft 365 Business Premium, check Defender for Business first, since it is included [3]. Choose ESET if older hardware makes speed the priority [2].
