The Reality of Zero Trust: How Alcatel-Lucent Enterprise and Versa Plan to Secure Multi-Site Business Networks
European organisations boost security with SASE and Zero Trust, unifying network access, enhancing compliance and streamlining multi-site IT operations
Organisations with multiple sites across France and Europe face a problem that gets bigger every day. Employees connect from more locations using more devices, while corporate networks become a patchwork of LAN, WLAN and cloud services. Traditional security models that worked when everyone sat in the office simply cannot handle the reality of modern business operations.
Alcatel-Lucent Enterprise has expanded its partnership with Versa Networks to tackle this challenge head-on. The two companies are combining their expertise to bring Zero Trust security to every network edge, promising to bridge gaps that leave many European enterprises vulnerable.
What’s Changed in Enterprise Security?
Zero Trust security means no user or device automatically gets access to network resources, even if they are inside the company’s perimeter. Every connection request must be verified and authorised. SASE (Secure Access Service Edge) takes this further by combining networking and security into a single cloud-based service.
This approach replaces the old castle-and-moat thinking where everything inside the corporate firewall was considered safe. Zero Trust Network Access (ZTNA) checks every user and device continuously, not just at login. Secure SD-WAN extends these principles across wide area networks, creating secure connections between remote sites and cloud services.
The new model matters because traditional LAN and WLAN controls cannot protect data that flows between multiple locations and cloud environments. When a French manufacturing company has factories in Lyon, offices in Paris and remote workers accessing systems from home, the old security model breaks down.
The Impact on Business Operations
For IT teams at multi-site European companies, the current approach often means managing different security tools at each location. A retail chain might have different firewall configurations at each store, while head office workers connect to cloud applications through separate systems.
Secure SD-WAN addresses these problems by creating consistent security policies across all locations. Instead of managing individual firewalls and VPN connections, IT teams can control access centrally while allowing local internet breakouts for better performance.
‘We are thrilled to strengthen our collaboration with Versa, a recognised leader in SASE and SD-WAN technologies,’ said Stephan Robineau, EVP of the Network Business Division at Alcatel-Lucent Enterprise. ‘Versa’s solutions align seamlessly with our commitment to provide high-performance and resilient networks, simplifying network operations and enhancing secure connectivity for enterprises and multi-site organisations.’
