Juniper Networks
Router and switch maker now run as HPE's networking division after the 2025 buyout.
On the record
Checkpoint: HPE reports next quarterly earnings with updated networking growth guidance
The call
Juniper no longer exists as a separate company; its routing and AI-networking business is now the fastest-growing part of HPE, while its old firewall line keeps losing ground to Fortinet.
Juniper Networks makes equipment and software that manages computer networks and keeps them secure. It is now owned by HPE (a large tech company) after a $14 billion purchase in mid-2025. Juniper is hard to replace in some areas, especially its new AI-powered troubleshooting tool called Marvis and its equipment for data centers running artificial intelligence. However, it faces real competition: Cisco already dominates in older networking products, and Fortinet has a much bigger share of the firewall market (14.5 percent compared to Juniper's 2.1 percent). The biggest question is whether HPE can keep Juniper's best engineers and products working smoothly after the takeover, because some key people have already left and the company has been forced by the government to license some of its technology to rivals, which could hurt profits over time.
Why
01
AI pressure: None apparent. AI data center build-out is feeding this business right now, driving switch and routing demand rather than replacing it. Could AI do the core job? Only partly.
02
Bigger players: Cisco Systems. Cisco still leads routing, switching, and security overall and is racing to match HPE Juniper's AI-native data center growth. Could a giant copy it? Probably.
03
What protects it. Junos routing lock-in with telecom carriers plus Mist AIOps data trained on years of customer network traffic.
What would change this call
Cisco announces or ships a competing AI-native networking/AIOps platform within 4-6 quarters. Would show Cisco closing the gap on HPE Juniper's fastest-growing segment.
HPE reports networking growth deceleration below 30% in upcoming quarterly earnings. Would show AI-cluster demand or integration momentum stalling from current 68-73% guidance.
Service-provider customers publicly move core routing away from Junos. Would show the crown-jewel lock-in (routing) is cracking, not just the weaker firewall line.

Questions people ask
- Does Juniper Networks still exist as an independent company?
- No. Juniper Networks ceased to exist as an independent public company on July 2, 2025, when HPE closed its roughly $14 billion acquisition. Juniper stock stopped trading on NYSE that day, and the business now operates as HPE Juniper Networking, a division within HPE's Networking segment, led by former Juniper CEO Rami Rahim.
- Is Juniper Networks (now part of HPE) profitable?
- Juniper's last standalone full year, 2024, showed net income of $288 million on $5.07 billion revenue. Post-acquisition it is folded into HPE's Networking segment, which posted 23.7% operating margin as of Q1 FY2026 (reported July 9, 2026), down year-over-year due to integration costs.
- Who owns Juniper Networks now?
- Hewlett Packard Enterprise (NYSE: HPE) owns Juniper Networks outright, having closed its acquisition on July 2, 2025 for an enterprise value of roughly $13.4 to $14 billion. Juniper is now a wholly owned subsidiary operating as HPE Juniper Networking.
- Could AI replace Juniper Networks' products or the engineers who use them?
- Juniper's own Marvis/Mist AIOps is automating much of the manual network troubleshooting work that IT staff used to do, and rivals like Palo Alto and Fortinet ship comparable LLM-based threat detection. As of July 2026 Juniper leans on proprietary telemetry and Junos installed base rather than AI-resistant hardware alone to stay differentiated.
- Is Juniper Networks (HPE division) growing or losing ground to Cisco?
- HPE's Networking segment, now including Juniper, grew 151.5% year-over-year to $2.7 billion in Q1 FY2026 (reported July 9, 2026), driven by AI-data-center demand, and HPE raised FY2026 networking growth guidance to 68 to 73%. Cisco remains the larger incumbent across routing, switching and security overall.
- Is Juniper's SRX firewall business struggling against Fortinet?
- Yes, in standalone firewall mindshare. PeerSpot data as of July 9, 2026 shows Fortinet's FortiGate holding about 14.5% mindshare versus Juniper SRX at just 2.1%, even though Juniper historically held a 24.8% firewall revenue share under Dell'Oro Group pre-2025 estimates.
