SASE deployment and configuration

CyberGrid designs and deploys Secure Access Service Edge (SASE), converging network connectivity and security into one cloud-delivered service so users get the same policy and protection from any location. We work with platforms including Palo Alto Prisma SASE and Cato SASE.

What SASE does

SASE brings SD-WAN, secure web gateway, cloud access security broker, zero trust network access and firewall-as-a-service together in the cloud.

Traffic is inspected close to the user rather than backhauled to a data center, which improves performance and keeps policy consistent.

What CyberGrid delivers

  • Current-state network and remote-access assessment
  • Architecture and phased migration plan
  • Tenant configuration, policy build and connector or branch onboarding
  • Replacement of legacy VPN with zero trust access where suitable
  • Support and policy optimisation after go-live

Who it is for

  • Distributed organisations with many branches and remote staff
  • Teams moving applications to cloud and SaaS
  • Companies looking to retire VPN concentrators and MPLS cost

We serve organisations across India and support customers globally, with offices in Bangalore, Hyderabad, Chennai and Trivandrum.

How we deliver SASE

  1. 1. Current-state review

    We document how users, branches and applications connect today: VPN concentrators, MPLS or internet links, proxies and firewalls. We also list which applications live in the data center, SaaS and public cloud.

  2. 2. Target architecture

    We design which functions move to the SASE service, such as secure web gateway, zero trust network access, CASB and firewall-as-a-service, and which stay on-premises, with a phased migration order.

  3. 3. Identity and policy design

    Access policy is built around user identity, device posture and application, not network location. We align it with your directory and multi-factor authentication.

  4. 4. Pilot and phased migration

    A pilot user group moves first. We then migrate users and branches in stages, retiring legacy VPN access as each group is confirmed working.

  5. 5. Operations and tuning

    We review logs, tune policies and handle change requests so access stays tight without blocking legitimate work.

What to look for when choosing

Which functions you need first

SASE bundles several capabilities. Most organisations get the fastest benefit from replacing legacy VPN with zero trust access, then adding web and SaaS controls.

Points of presence and latency

Check where the provider has presence relative to your users and applications. Poor proximity adds latency that users will notice.

Integration with existing tools

Identity provider, endpoint agent, SD-WAN and logging should integrate cleanly. Gaps here create manual work later.

Single vendor or best of breed

A single-vendor SASE simplifies operations. Combining separate products offers flexibility but needs more integration effort.

Compliance alignment

Zero trust access and centralised logging help demonstrate access control and monitoring requirements under ISO 27001, RBI guidance and the DPDP Act, particularly for remote users and third-party access.

Common scenarios

Retiring a legacy VPN

Remote staff connect to named applications through zero trust access, so a compromised device no longer gets the whole network.

Securing branch internet access

Branches send web traffic to the SASE service for filtering, instead of backhauling it to head office.

Controlling SaaS use

A CASB function shows which cloud apps staff use and enforces rules on sharing and uploads.

Mistakes to avoid

  • Moving everything at once. A staged migration by user group finds problems early and limits business impact.
  • Copying network-based rules. SASE policy works best when written around identity and application, not IP ranges.
  • Forgetting legacy applications. Some older apps need special handling. Test them in the pilot.

Frequently asked questions

What is SASE in simple terms?

SASE delivers networking and security together as a cloud service, so every user and branch gets the same protection regardless of location.

Is SASE the same as SD-WAN?

No. SD-WAN is the connectivity layer. SASE combines SD-WAN with cloud-delivered security services.

Do we have to replace our firewalls to adopt SASE?

Not necessarily. Many organisations adopt SASE in phases, starting with remote users or selected branches, and keep data center firewalls.

How long does a SASE rollout take?

It depends on the number of sites and users and how many legacy systems are being replaced. We phase rollout so each stage can be validated.

Does SASE replace our firewall?

Not always. SASE moves many inspection functions to a cloud service, but data center and branch firewalls often remain for local segmentation. We design what stays and what moves.

Can SASE replace our VPN?

Zero trust network access, a core SASE component, is commonly used to replace traditional VPN. It grants access to specific applications instead of the whole network.
