If you have landed here, you are likely searching for a specific legacy or on-premise security agent: cna-windows-k9-installer-6-3-4-en.exe .
This installer typically corresponds to Check Point’s Harmony Endpoint (formerly SandBlast Agent) or a similar Next-Generation Firewall (NGFW) endpoint client, specifically the "K9" build for Windows, version 6.3.4, English.
Important Security Note: As of 2024-2025, version 6.3.x is considered a legacy version. Check Point strongly recommends updating to the latest R8x (or higher) agents to avoid security vulnerabilities and compatibility issues with Windows 11/Server 2022.
Q1: Is there any official download link still working?
No. Symantec/Broadcom removed all official K9 download pages in 2019.
Q2: Can I use the old installer on Windows 11?
Unlikely. Driver conflicts and browser compatibility will probably cause installation failure or system instability.
Q3: What if I find a website offering the exact filename?
Treat it as suspicious. Scan it with VirusTotal, check the digital signature, and run it only in a sandbox. Most such sites distribute malware.
Q4: Does K9 still block websites after discontinuation?
Yes and no. The local filter may still work based on its last blocklist (circa 2018), but new domains won’t be categorized, and HTTPS sites will produce certificate errors.
Q5: Will my antivirus delete the installer?
Likely yes. Most modern antivirus suites (Windows Defender, Malwarebytes, etc.) detect K9 as a PUP or unsecured application due to its age and network interception method.
The biggest danger when searching for “cna-windows-k9-installer-6-3-4-en.exe download” is that official sources no longer exist. Cybercriminals exploit this exact scenario by packaging malware, adware, ransomware, or trojans inside fake installers that use similar filenames.
