Hello,
Unfortunately, Check Point only provides downloads for their most recent version of firewall software. However, you can find previous versions of Check Point firewall software on third-party websites or obtain them from Check Point's customer support. However, please note that downloading older versions of firewall software from unauthorized sources or torrents can potentially expose your network to security vulnerabilities and malicious attacks.
If you are a Check Point customer, you can contact Check Point's support team and inquire about access to previous versions of their firewall software for testing purposes. They might also provide you with virtual machine images that you can run on your lab environment.
I hope this information helps!
