| Best for | Backblaze is a strong fit for small businesses where most critical data lives on employee laptops and desktops rather than on servers. Professional services firms—accountants, consultants, photographers, video editors, and small law offices—benefit most because their work product is tied directly to individual machines. Retail shops and small agencies with two to twenty-five computers get immediate value from the per-seat flat pricing, which scales predictably. It works especially well for businesses that have zero dedicated IT staff and need a solution that an owner or office manager can deploy and forget. Remote and hybrid teams also benefit since the backup happens wherever the laptop is connected to the internet. | Duo Security fits small and mid-sized businesses that rely heavily on cloud applications—accounting firms protecting financial portals, healthcare practices safeguarding patient data, e-commerce operations locking down their payment and fulfillment platforms, and remote-first teams accessing shared servers or VPNs from multiple devices. It's particularly well-suited for businesses that must demonstrate basic security compliance to insurance carriers or enterprise clients, since Duo's audit logs and policy enforcement are easy to document. Managed service providers supporting multiple SMB clients also find Duo's multi-tenant admin console practical for rolling out MFA at scale without juggling separate accounts. |
Backblaze
Flat-rate, unlimited cloud backup for every business Mac and PC at $99 per computer per year—no file-size caps, no surprises.
Picture this: a two-person accounting firm wraps up tax season, and the next morning one employee's laptop hard drive fails completely. No recent backup means weeks of client files, spreadsheets, and correspondence are simply gone. That single incident can cost more in recovery a…
Key features
- Continuous automatic backup runs silently without manual intervention or scheduling
- Unlimited data per computer—no file size or file type restrictions apply
- Flat annual pricing per computer simplifies IT budget forecasting for small teams
- Web-based restore lets any authorized user retrieve files from a browser
- External drive backup covers USB and Thunderbolt drives connected at backup time
- Business Groups dashboard gives owners centralized visibility across multiple computers
- Optional physical restore via mailed USB drive speeds large file recoveries
- Version history retains deleted or changed files for up to one year by default
Limitations
Backblaze backs up computers, not servers—Windows Server editions and NAS devices are not supported under the standard personal or business computer plans (Backblaze B2 cloud storage is a separate product for those use cases). The initial backup of a large hard drive can take several days to several weeks depending on upload speed and data volume, which is a real gap in protection during onboarding. Files on external drives must be connected at the time of backup or they'll be flagged as missing and eventually removed from the backup set. It is not a sync tool, so it cannot replace Dropbox or Google Drive for real-time file sharing. Verify current retention limits and add-on costs on the vendor site before assuming defaults meet your needs.
Duo Security
Duo Security stops credential theft cold by requiring a second proof of identity before anyone enters your business systems.
Picture this: an employee clicks a convincing phishing email, types in their password, and hands it straight to an attacker. Without a second layer of verification, that's game over for your accounts. Duo Security exists specifically to close that gap. When a login attempt fires,…
Key features
- Push notification approvals let users verify logins with a single phone tap
- Free plan covers up to 10 users with core MFA at no cost
- Device health checks block logins from outdated or compromised endpoints
- Self-service enrollment lets employees onboard without IT intervention
- Single sign-on (SSO) consolidates access to multiple apps under one secure login
- Trusted device policies reduce friction for recognized, compliant hardware
- Detailed authentication logs give admins a timestamped audit trail of every login
Limitations
The free plan's 10-user cap means most growing businesses will hit a paywall relatively quickly, and Cisco's enterprise pricing tiers can feel steep compared to lightweight MFA alternatives once you scale past 50 or 100 seats. Integrating Duo with legacy, on-premise, or custom-built applications requires RADIUS or LDAP configuration that can frustrate non-technical owners. The mobile app dependency—while convenient for most—creates friction for staff who don't use smartphones or work in environments where phones are restricted. Additionally, Duo's broader feature set (device trust, SSO, adaptive policies) is only unlocked on higher-paid tiers, so the advertised free plan reflects a limited slice of the full product.
