Category: Security Suite (SASE/EDR)Verified for 2025
Top Recommended Replacements
Cloudflare Zero Trust
FREEBest SASE/Network Replacement
Why we like it
Replaces 'Harmony Connect' and 'Harmony Browse' completely; free for up to 50 users; includes DNS filtering, browser isolation, and ZTNA remote access; blocks malware at the network level.
Keep in mind
Does not include an 'Antivirus' agent for the endpoint itself; requires a separate tool for file scanning.
Wazuh
Best Endpoint (EDR) Replacement
Why we like it
A massive open-source security platform that replaces 'Harmony Endpoint'; provides XDR, file integrity monitoring, and malware detection; highly customizable for technical teams.
Keep in mind
Requires setting up a management server; steeper learning curve than a 'install and forget' antivirus.
Sophos Home / Intercept X
FREEBest Managed AV
Why we like it
Offers a cloud dashboard similar to Check Point's Infinity Portal to manage up to 3 devices for free; includes enterprise-grade malware detection and AI threat prevention.
Keep in mind
The free version has reduced features compared to the full 'Intercept X' enterprise product; web filtering is basic.
Sophos Intercept X for Mobile
FREEBest Harmony Mobile Replacement
Why we like it
100% free app for iOS and Android; includes a QR code scanner for malicious links, Wi-Fi security checks, and an authenticator; identical engine to the paid enterprise version.
Keep in mind
Management is local to the device unless you buy the central management license.
Sublime Security
FREEBest Harmony Email Replacement
Why we like it
An API-based email security platform (like Harmony Email); the 'Platform Free' tier covers up to 3,000 emails/month; allows you to write custom rules to block phishing and BEC attacks.
Keep in mind
Requires a Google Workspace or Office 365 environment; more 'hands-on' rule configuration than Check Point's automated AI.
Twingate
FREEBest Remote Access (VPN) Alternative
Why we like it
Replaces the 'VPN' aspect of Harmony Connect; free for up to 5 users; allows secure, hidden access to internal servers without exposing them to the internet.
Keep in mind
Strictly for access control; does not inspect the traffic for malware like a full SASE firewall.
ZoneAlarm Free Firewall
FREEBest 'Lite' Version
Why we like it
ZoneAlarm is actually owned by Check Point; uses the same core threat intelligence engine as Harmony for a fraction of the complexity (and cost).
Keep in mind
Ad-supported; the interface is aimed at consumers, not IT admins; lacks central management.
NextDNS
FREEBest for DNS Filtering
Why we like it
Blocks phishing domains and C&C servers before they reach your device; free for 300,000 queries/month; works on mobile and desktop instantly.
Keep in mind
Does not inspect the content of the page, only the domain name.
Velociraptor
Best for Forensics/Hunting
Why we like it
If you use Harmony for its 'Threat Hunting' capabilities, Velociraptor is the open-source king of digital forensics and incident response (DFIR).
Keep in mind
Extremely technical; intended for security analysts, not casual users.
Elastic Security (Free Basic)
FREEBest SIEM Integration
Why we like it
The Elastic Agent includes free malware prevention and ransomware protection; feeds data directly into the Elastic Stack for analysis.
Keep in mind
Requires an Elastic Stack backend (cloud or self-hosted) to view the alerts.
Bitdefender Antivirus Free
FREEBest 'Set and Forget'
Why we like it
Extremely lightweight; uses one of the highest-rated detection engines in the world; silent running mode.
Keep in mind
Zero configuration options; you cannot tweak sensitivity or exclusions easily in the free version.
Quad9
FREEBest Privacy DNS
Why we like it
A set-and-forget DNS (9.9.9.9) that uses threat intelligence from 12+ providers (including IBM X-Force) to block malicious domains for free.
Keep in mind
No dashboard; you cannot see what was blocked or whitelist specific domains.
