Palo Alto Prisma Access
Palo Alto Networks · Network Security
SASE and zero-trust network access for the hybrid workforce
Overview
Palo Alto Prisma Access is a cloud-delivered security platform (SASE) that provides secure access to applications for remote and branch users. It combines next-gen firewall, CASB, SWG, and ZTNA in a single cloud service, replacing legacy VPN and perimeter security.
UK Pricing
Enterprise pricing — typically £15–30+/user/mo depending on modules. Contact Palo Alto for quote.
Target Size
500+ users or organisations with complex multi-cloud / remote-first requirements
Why Use It
For UK organisations with a hybrid workforce and multi-cloud environment, Prisma Access delivers enterprise-grade security without the overhead of on-premises security appliances. Ideal for financial services, legal, and healthcare sectors.
Why Not
For medium businesses under 300 seats, FortiGate or even Meraki with Umbrella provides better value. Prisma Access is best justified when you have complex branch + remote + cloud requirements.
Pros & Cons
Pros
- Best-in-class NGFW capabilities delivered as cloud service
- ZTNA eliminates legacy VPN for remote access
- Single policy across remote users, branch offices, and cloud workloads
- AI-powered threat prevention (Cortex AI)
- Strong compliance reporting for regulated industries
Cons
- Significant cost — hard to justify for sub-500 seat organisations
- Complex to implement without a skilled Palo Alto partner
- Licensing model (credits) can be confusing
- Requires significant change management vs. legacy VPN
- Overkill for organisations with simple network requirements
How to Get the Most Out of It
- Start with ZTNA for a specific application before migrating all VPN traffic
- Use Security Policy Optimiser to identify and clean up redundant firewall rules
- Enable DNS Security to block malicious domains before connections are established
- Use Cortex Data Lake for unified logging across all Palo Alto products
- Engage a certified Palo Alto partner for initial deployment — complexity rewards specialist knowledge
AI: What's New
Claude AI# Prisma Access Updates: What You Need to Know
• **AI Agent Security is Now a Core Focus** – Prisma Access is evolving to secure AI agents and autonomous systems at scale through a unified AI gateway. This means you'll need to configure policies specifically for AI workloads, not just traditional user/device traffic, to prevent agents from being exploited or going rogue.
• **Evasion-Resistant Threat Prevention** – The platform is shifting to counter sophisticated evasion techniques that bypass traditional detection. Expect enhanced behavioral analysis and real-time threat correlation in your security policies, requiring you to review and update your threat prevention rules for better coverage against adversaries actively trying to evade detection.
• **Enterprise AI Infrastructure Protection** – Prisma Access now addresses security requirements for AI factories and autonomous defense systems. If your organization is deploying AI infrastructure or using autonomous security tools, you'll need to ensure Prisma Access policies govern these critical systems with the same rigor as production networks.
