Who is Versa Networks?

Founded in 2012, Versa Networks seeks to deploy a single software operating system, called VOS, to converge and integrate cloud and on-premises security, networking, and analytics. Using VOS, Versa enables customers and service providers to deploy SASE and software-defined wide area network (SD-WAN) solutions. Versa Networks remains a privately-held company backed by venture funds such as Sequoia Capital, Verizon Ventures, and Comcast Ventures.

Versa Unified SASE

Versa’s Unified SASE Platform provides a single software solution to control, secure, and analyze network flow, user access, and resources. The platform, previously called Versa Secure Access or Versa Secure Access Fabric, connects to both cloud and local resources with ease.

Versa was recognized as a Challenger in the 2023 Gartner Magic Quadrant, and the Versa Unified SASE platform delivers the required six key SASE capabilities:

  1. Centralized control through Versa Concerto, a consolidated management console that provides a single interface to manage other components and policies
  2. Monitored network status pulled from Versa’s software-defined wide area network (SD-WAN) capabilities that provide reports, analytics and control over network operations performance and security
  3. Monitored user activity and data loss prevention (DLP) analysis through the Versa Secure Internet Access (VSIA) tool
  4. Inspected and decrypted traffic that blocks malware and malicious URLs through a centralized control and filtering through VSIA’s secure web gateway (SWG) and Firewall-as-a-Service (FWaaS) capabilities
  5. Controlled access to data and resources based upon user, device, and permissions through Versa Secure Private Access (VSPA) zero trust network access (ZTNA) and SD-WAN capabilities as well as VSIA’s cloud access security broker (CASB), and domain name service (DNS) security capabilities
  6. Secured cloud-based assets such as applications, websites, and Software-as-a-Service (SaaS) resources through VSIA’s SWG and FWaaS capabilities

Versa Unified SASE harnesses artificial intelligence (AI) and machine learning (ML) algorithms to quickly detect anomalies and provide powerful analytics, control and response capabilities. The SASE solution also provides additional security to users through remote browser isolation that keeps the endpoint segregated from the corporate information.

The primary service components of the Versa SASE solution include:

  • Versa Analytics powers the exploration of SASE, SD-WAN, and other SASE operations and security data; built for the Secure Cloud IP Platform; multi-tenant
  • Versa Secure Access Client (VSAC) App extends the SASE solution to endpoints and provides an isolated browser on Windows, macOS, iOS, and Android devices
  • Versa Concerto provides the single orchestration platform for an organization to use to deploy, monitor, operate, and analyze a SASE deployment
  • Versa Secure Internet Access (VISA) provides cloud-hosted secure web gateway capabilities such as multi-factor authentication (MFA), stateful firewall, web filtering, URL traffic management, cloud-based CASB, DLP, and deep packet scanning
  • Versa Secure Private Access (VSPA) enables cloud-hosted ZTNA capabilities for Versa SASE with visibility, awareness, and control over users, applications, and fully encrypted network connections
  • Versa Operating System (VOS) provides the base OS to integrate and power all of the Versa components
  • Versa CSG Appliances provide local appliances to connect to cloud-based Versa SASE components or to connect locally hosted SASE and SD-WAN implementations

Versa Titan SASE

For Lean IT environments, Versa offers the stripped down Versa Titan deployment that allows for full SASE capability through a single hardware unit deployed in each branch office and the Versa Titan Mobile App. IT teams can still apply policies, receive reports, and view analytics using the Versa Titan Portal.

Pricing & Delivery

Pricing for Versa’s SASE product was originally called Versa Secure Access and announced in 2020 to start at $7.50 per user per month without limitation for the number of devices. However, Versa no longer publishes prices for their SASE solution overall and limited information can be obtained without a formal sales estimate.

A free trial is available for up to 100 users for organizations with 5,000 or more employees. This size limit suggests that Versa SASE is best suited for large enterprises.

Some limited information is available on tiers and appliances for some Versa components:

  • Versa Concerto can be deployed in two main configurations on high-end x86 server clusters with 3 nodes (virtual or physical):
    • 8 cores with 16 GB of DRAM supports up to 150 tenants and 4,000 branches
    • 12 cores with 32 GB of DRAM supports up to 250 tenants and 10,000 branches
  • Versa Secure Internet Access (VISA) is offered in three service tiers:
    • Essential Tier: cloud-based app and SaaS access, enterprise authentication, bandwidth control and traffic priority management, web filtering, and real-time security updates
    • Professional Tier: includes Essential Tier plus SSL/TLS Proxy, network-based antivirus protection, as well as inline CASB and malware protection
    • Elite Tier: includes Professional Tier plus clientless SaaS application management, DLP, and advanced threat protection
  • Versa Secure Private Access (VSPA) has two tiers of service:
    • Essentials Tier: intelligent gateway selection, enterprise authentication, site-to-site data center tunnels, network obfuscation, and whitelisting for up to 10 applications
    • Professional Tier: adds whitelisting for unlimited applications, ZTNA policies based on device posture, and app based traffic steering

Versa Cloud Security Gateway (CSG) Appliances

The best available pricing information can be found for Versa CSG appliances, both physical and virtual, which enable connections between a remote network and the rest of the Versa environment. While some devices may connect directly to Versa secure gateway functions, some organizations will prefer to use the traditional hub and spoke network models and use Versa CSG appliances as the gateway between secured networks.

Physical appliances provide functionality for routing wide area networks (WANs), stateful firewalls, SD-WANs, NGFW, antivirus, intrusion prevention services (IPS), and unified threat management (UTM) capabilities for local networks. Hardware configurations and options deliver:

  • Copper or fiber ethernet ports with speeds from 10 Mbps to 10 Gbps
  • Embedded enterprise class WiFi access points
  • Legacy WAN network support using non-Ethernet standards (ADSL2/VDSL2 or T1/E1)
  • Single or dual enterprise class Long Term Evolution (LTE) modules
  • 5G Native modem options for the CSG700 and CSG1000 families of appliances
  • Support for 3rd party virtual machines to deploy software from other suppliers
  • Passively or actively cooled designs

Hardware starts at $500 for the low-end Versa appliances which can only be purchased through distributors, value added resellers (VAR), and other IT integration sources. Prices are not generally published for higher end hardware or virtual appliances. Virtual Appliance supports most major virtualization options:

  • Amazon AWS (EC2)
  • KVM on CentOS 7.7. Ubuntu 18.04, and Ubuntu 20.04
