  In a zero-trust model, no entity is inherently trusted, regardless of its location or identity. This approach assumes that all entities, both internal and external, are potential threats and must be verified before being granted access to network resources.

• Perimeter-based:

  Perimeter-based security relies on the concept of a well-defined network boundary, with security controls focused on protecting the perimeter of the network. This approach assumes that entities outside the perimeter are untrusted, while those within the perimeter are trusted.

The choice between a zero-trust and perimeter-based approach depends on an organization's specific security requirements and risk tolerance. Zero-trust is more suited for modern, dynamic environments where traditional perimeter defenses may be insufficient to protect against sophisticated attacks. Perimeter-based security, on the other hand, may be more appropriate for organizations with a relatively static network infrastructure and a lower risk tolerance.

Subscription vs. Perpetual licensing

The choice between subscription and perpetual licensing is a key consideration when evaluating Zscaler and Palo Alto Networks. Each licensing model has its own advantages and disadvantages, and the best choice for an organization will depend on its specific needs and budget.

• Flexibility: Subscription-based licensing offers greater flexibility than perpetual licensing. With a subscription, organizations can scale their usage up or down as needed, without having to make a large upfront investment. This can be beneficial for organizations that are experiencing rapid growth or that have fluctuating security needs.
• Cost: Perpetual licensing typically requires a larger upfront investment than subscription-based licensing. However, perpetual licenses can be more cost-effective in the long run, especially for organizations that have stable security needs and do not anticipate needing to scale their usage significantly.
• Support: Subscription-based licensing typically includes support from the vendor. This can be a valuable benefit, especially for organizations that do not have the in-house expertise to manage their security infrastructure.
• Upgrades: With a subscription-based license, organizations are entitled to software updates and upgrades as they become available. This ensures that organizations are always running the latest version of the software, with the latest security features and bug fixes.

Ultimately, the best way to decide which licensing model is right for an organization is to compare the costs and benefits of each option and determine which one best meets the organization's needs.
