2. Erratic Application Access – Users experience latency and increased internet risks when
accessing applications remotely hosted in the cloud or a data center.
3. Inconsistent Policies – The inconsistent configuration policies across different sites lead to
routing and security performance issues. Many inbound or outbound malicious activities aren’t
blocked, and a latency is experienced while accessing corporate sensitive applications.
4. Access to all corporate data – Traditional solutions, such as VPN, are perimeter-based and
grant full access to the enterprise’s data once a user is logged in.
5. Insufficient visibility resulting in operational inefficiencies – There was no single source of
truth for user behavior analytics, device posture assessment, or security event correlation.
6. Operational Inefficiencies – When incidents occurred, the operations team had to manually sift
through disjointed logs from multiple systems, resulting in a prolonged mean time to resolution
(MTTR).

Secure Access Service Edge (SASE) Solution

A well-thought-out and designed SASE solution addresses all the enterprise’s demands.

SASE Gateways

• Cloud-Native Architecture – Cloud-native architecture is easily scalable, allowing for horizontal
or vertical scaling based on demand. This approach ensures a design with high availability and
fault tolerance across all the SASE gateways. This architecture also provides the following
benefits.
• Single Software Architecture – The unified software solution provides integrated networking,
including Software-Defined Wide Area Network (SDWAN), and security service edge (SSE)
features, such as Secure Web Gateway (SWG), Cloud Access Security Broker (CASB), Zero
Touch Network Access (ZTNA), and Firewall-as-a-Service (FWaaS). The traffic passing through
the software architecture is analyzed only once, which improves performance, reduces
processing overhead, and lowers the risk of security vulnerabilities.
• Zero Trust Principle – Users are granted the least privileged access, allowing them to view only
the data assigned to their role. Throughout the network, users and their devices are continuously
authenticated and assessed before access is permitted.
• Multitenancy – Enterprises run multiple tenants to keep important and sensitive data traffic
separate from public traffic, such as hosting a public tenant for WIFI for guests and non-
employees. Additionally, unique traffic steering and security policies are tailored to specific
business needs. A significant benefit for enterprises is the ability to quickly create an extra lab
tenant to test new configuration policies and software versions before deploying them in
production.
• Consistent Policy Enforcement – The IT administrator can create one or multiple policies and
implement them across all SASE gateways. These policies can now include networking services
configurations, such as application-aware or SLA-based routing, DHCP, DNS, QoS, VLANs,
VRRP, and security services like URL filtering, IP filtering, file filtering, DNS filtering, malware
scanning, anti-virus, Data Loss Prevention (DLP), web and cloud access control, and more. A
