Today, enterprises need flexibility at every layer of the network and application stack. Users need secure, authenticated access no matter where they are: at the office, on a mobile device, or working from home. The changing shape of these network perimeters is phasing out traditional VPNs and driving the adoption of Zero Trust Network Access Models (ZTNA).
Last year, Gartner’s Market Guide for Zero Trust Network Access (ZTNA) projected that by 2023, 60% of enterprises will phase out VPN and use ZTNA instead.
The advantage of ZTNA models is they offer way more granularity. This granular level of control compliments the identity-driven approach to network access that SASE (Secure Access Service Edge) demands allowing resources of the modern enterprises just the right degree of access.
Single pane of glass management
Through SASE, teams get unified views into infrastructure deployments (including for cybersecurity), network policy configurations, and comprehensive reports. It all adds up to more holistic and agile control across the entire enterprise architecture.
A SASE platform combines cloud security with comprehensive WAN functionality, with both of these capabilities building upon one another. While cloud security enables local internet breakouts (for eliminating latency from backhauled architectures), it does nothing to overcome the overall unpredictability of internet connections. SD-WAN and WAN optimization ensure changes in network performance do not impact employee experience
For enterprises that have invested serious time and resources in elaborate on-premises setups, managing complex webs of cloud-based security services, or are still adjusting to the future of remote work, SASE adoption may seem intimidating — but it doesn’t have to be especially if you choose to align yourself with an MSP like Intelys Telecom.
What does a SASE strategy involve?
- Building and managing networks
Next Generation networking technologies like SD-WAN enable organizations to establish private corporate networks without the assistance of hardware routers or multiprotocol label switching (MPLS) circuits. SD-WAN provides a secure edge at the branch, facilitates direct internet access and optimal routing to the Internet which is a fundamental component to SASE. The abstraction of the underlay and overlay enables SD-WAN to provide last mile resilience, quick failover, and optimization of WAN traffic.
- Connecting users to applications
SASE technologies like Zscaler or Netskope protect users against external and internal threats with a zero-trust security model, in which user identity and access is granted based on a combination of factors.
- Filtering Traffic
A secure web gateway (SWG/Hosted Proxy) prevents cyber threats and data breaches by filtering unwanted content from web traffic, blocking unauthorized user behaviour, and enforcing company security policies. SASE uses a cloud native approach which means your security stack is hosted in the cloud, providing endless scalability as well as increased performance and resilience
- Protecting applications and infrastructure
Cloud-based firewalls protect cloud infrastructure and applications from cyber-attacks through a set of security features that includes URL filtering, intrusion prevention, and uniform policy management.
- Securing Data
A cloud access security broker, or CASB, secures confidential data through access control and data loss prevention, reveals shadow IT, and ensures compliance with data privacy regulations.
No matter where applications are hosted, or employees reside, enterprise connectivity needs to be secure and fast.
