Teams look past Palo Alto Networks Next-Generation Firewall when a hardware refresh is due, when the sales-only buying route slows a small project, or when they want a vendor with a smaller product range. Most move to Sophos Firewall, Fortinet FortiGate or WatchGuard Firebox, and the open source route runs through OPNsense or pfSense.
Short answer: The closest replacements for Palo Alto Networks Next-Generation Firewall in our network firewall software ranking are Sophos Firewall, Fortinet FortiGate and WatchGuard Firebox. Choose Sophos Firewall if you want a smaller product range and a bundle instead of separate services. The other 11 entries come from our Best Network Firewall Software in 2026 list as well, and every one is set against Palo Alto Networks Next-Generation Firewall specifically, with a note on the cases where Palo Alto Networks Next-Generation Firewall should stay.
Vendors can pay for more visibility on this website, for example a higher place in a ranking or more room on a page. Commercial relationships can also affect which products we feature and how prominently. Every vendor link is marked the same, whatever the arrangement behind it. The first three alternatives go to challengers, vendors outside the best-known brands in a category, wherever the category has them; the established names follow in their ranked order. How it works: placement disclosure · editorial process.
Vendor tables show the PA-3000 and PA-5000 series already at end of life, and the PA-5200 and PA-3200 series end on August 31, 2028. A fleet bought in one wave tends to expire in one wave, so the refresh arrives as a single project.
Standard support for PAN-OS 10.2 ended on August 27, 2025, and PAN-OS 11.1 and 11.2 follow in May 2027. Extended support runs only to the hardware end-of-life date. Teams on older appliances face an upgrade path or a replacement decision.
The contact page offers a North America sales number and an International Sales link, and no price or plan page exists on the sites we opened. Buyers who want a figure before a meeting, or a partner route they can compare, may prefer a vendor that publishes more.

Sophos sells XGS Series appliances and also protects public, private and hybrid cloud. Subscription bundles are named Xstream Protection and Xstream Plus, which gives a shorter menu than a list of separate security services. Published figures are absent, so a quote is still required.

Fortinet builds FortiGate around its own security and networking ASICs, as its page words it, and groups FortiGuard services into ENT, UTP and ATP bundles. A FortiGate-as-a-Service option exists for teams that prefer not to run appliances. Costs are not shown on the product page.
Switch from Palo Alto Networks Next-Generation Firewall if you want appliance performance with named subscription bundles and a hosted option.
WatchGuard offers tabletop and rackmount appliances, FireboxV for virtual machines and Firebox Cloud. Licensing runs through Flexible Network Security Services, and the page offers a Get Pricing link instead of a price. It targets distributed small and midsize sites more than very large estates.
Switch from Palo Alto Networks Next-Generation Firewall if you run many small sites and want virtual and cloud variants of one line.
OPNsense is free software under a simplified two-clause BSD license and is also sold as appliances and an OVA image. A paid Business Edition has a Buy now link without a visible price. You trade a vendor support desk for an open codebase you can inspect.
Switch from Palo Alto Networks Next-Generation Firewall if you want to inspect and modify the firewall source and pay only for support.
pfSense Plus runs on Netgate appliances or as cloud virtual appliances on AWS and Azure, while a Community Edition stays free. The model avoids a stack of per-service subscriptions. It is a different design from App-ID rules, so policy must be rebuilt rather than carried over.
Switch from Palo Alto Networks Next-Generation Firewall if you want one flat license across hardware, virtual and cloud instances.
Check Point sells hardware firewalls with an OpEx option, a subscription paid monthly or annually. On-premises, cloud and SASE environments are managed from one place. The model fits finance teams that want hardware cost spread over time, and no price is published on the page.
Switch from Palo Alto Networks Next-Generation Firewall if you would rather pay for hardware and protection as one recurring subscription.
SonicWall organizes its range into TZ, NSa and NSsp hardware families plus the NSv virtual firewall, which is aimed at hybrid and multi-cloud use. Security services come as simplified licensing suites. It is a plain ladder by site size, with no price on the product page.
Switch from Palo Alto Networks Next-Generation Firewall if you need one family that scales from branch office to large site.
Cisco covers models from the 200 and ISA3000 branch and industrial units up to the 6100 for data centers. Management runs through Firewall Management Center or Cisco Cloud Control. It suits shops already built on Cisco networking and gives a wide industrial range.
Switch from Palo Alto Networks Next-Generation Firewall if your network already runs on Cisco and you need industrial or branch models.
Stormshield offers physical appliances and Elastic Virtual Appliances (EVA), with no cloud hosting described on the page we read. It lists a sales number and contact form in place of a price. Buyers who care about the vendor being French-based will find that fact in the category table.
Switch from Palo Alto Networks Next-Generation Firewall if you want physical and virtual appliances from a vendor that sells through partners.
Barracuda designed CloudGen as a firewall for the cloud, deployable on premises or in Azure, AWS and Google Cloud. It advertises zero-touch rollout to remote sites and an option for managed service providers. No licensing model or price is shown on the page.
Switch from Palo Alto Networks Next-Generation Firewall if you roll firewalls out to many remote sites or buy through a managed service provider.
Forcepoint runs on physical appliances, virtual machines and cloud images, all managed centrally through the Secure Management Console (SMC). One console for every form factor is the main pitch. The page states no licensing terms or price, so a partner quote is the next step.
Switch from Palo Alto Networks Next-Generation Firewall if you want one management console across appliances, virtual machines and cloud images.
Zyxel sells a business NGFW line managed from a single console, with flexible licensing for security, management and reporting. The Nebula cloud platform is mentioned, but the page does not say whether the firewalls run on it. No prices appear on the overview page.
Switch from Palo Alto Networks Next-Generation Firewall if you want a lower-end firewall line with licenses split by function.
Stay if you run a large or hybrid estate with analysts who read the telemetry and use one vendor from branch appliance to virtual machine, Kubernetes sidecar and managed AWS service. A single Panorama pair can manage up to 5,000 firewalls, and existing App-ID and User-ID policy is expensive to rebuild. If your appliances still have years of supported life, a move gains little.
We found no migration tool or document on the vendor's pages we could open, and the Expedition page returned a not-found error. Treat the rule base as something to review and rewrite. App-ID based rules rarely map one to one onto port and service rules.
Match each appliance to the end-of-sale and end-of-life dates in the vendor table, then run old and new firewalls in parallel until traffic is verified. A hardware end-of-life date in 2028 gives time, but a PAN-OS standard support end in 2027 may arrive sooner.
We could not verify a configuration export procedure, because the export document we tried returned a not-found error. The vendor does state that the PAN-OS and Panorama XML API support integration and automation, so scripted extraction of rules is likely possible, and you should confirm it in the current API guide.
No price appeared on any vendor page we opened, and the pricing page we tried returned a not-found error. Buying runs through sales contact, with a North America sales number and an International Sales link. Ask for the eight Cloud-Delivered Security Services to be itemized in the quote.
It depends on the family. The PA-5200 and PA-3200 series reach end of life on August 31, 2028, and the PA-5450 reaches it on November 21, 2031. The PA-400 and PA-440 to PA-460 families reach it on March 21, 2032. Extended PAN-OS support runs to those dates.
PAN-OS 12.2, 12.1, 11.2 and 11.1 are listed as current on the vendor docs index, while 11.0, 10.1, 10.0, 9.1, 9.0 and 8.1 are marked end of life. Standard support for 11.2 ends May 2, 2027 and for 11.1 May 3, 2027.
Only part of it. The Essentials tier is included at no cost for all NGFW, software firewall and SASE customers, and offers centralized visibility through the Strata Logging Service. The Pro tier is described as unlocking more, but the page shows no price or term for it.
You lose Panorama, which manages up to 5,000 firewalls per high-availability pair, so check what the new vendor offers. Several alternatives here name a central console, for example Forcepoint's SMC and Cisco's Firewall Management Center. Compare it against your device count before signing.
Every price, plan limit and product statement about Palo Alto Networks Next-Generation Firewall here was read on the vendors' own pages on November 14, 2026. Either can change at any time, so read the figures as of that day.
