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# Key Prisma Access Updates for Daily Users
• **AI Agent Security Integration** – Prisma Access now includes a unified AI gateway to secure and govern AI agents at scale. This means you'll have native controls to inspect and protect agentic AI traffic alongside traditional user/app traffic without separate point solutions.
• **Enhanced Evasion Detection** – The platform has shifted to address AI-powered and evasion-based threats that traditional signatures miss. Expect improved real-time threat prevention that catches sophisticated attacks attempting to bypass older detection methods.
• **Expanded Autonomous Defense Capabilities** – Prisma Access ecosystem has grown to include autonomous threat response features, reducing manual intervention needs. You'll see faster incident containment without constantly escalating to your security team.
