Essential benefits of single-vendor SASE

Enterprises have bought into the benefits of SASE. According to a recent press release by Dell’Oro Group the SASE market will grow to $97 billion in five years. When implemented right, with the right vendor, it makes the network more efficient and more secure while reducing total cost of ownership. A win, win, win! But why is single-vendor unified SASE significantly more beneficial than just SDWAN + SSE from different vendors?

The many advantages stem from the fact that it requires twice the effort to use two separate products, along with the need for customization where integration points are not standards-based. Training, provisioning, integration, management, troubleshooting, network tuning, and security operations correlation, detection and response efforts are all compounded in their effort. Here below is a list of the top 10 considerations.

How does single-vendor SASE reduce implementation and operational costs?

Teams don’t need to learn two platforms, avoid manual IPsec tunnel provisioning for branches and data centers, and remove the overhead of running multiple consoles, support relationships, and patching cycles for separate vendor systems.

1. Lower implementation costs

Using single-vendor SASE lowers implementation costs.

• IT teams do not have to learn products from two different vendors
• They do not need to provision thousands of IPsec tunnels manually for each branch and data center in order to access SSE gateways
• Also, by using unified policies they do not need to create custom policies to integrate separate network and security systems

2. Lower operational costs

Using single-vendor SASE lowers operational costs, saving time and money.

• IT teams do not have to use multiple consoles to monitor network and security activities
• They do not have to contact support at different vendors
• They do not need to implement software patches for vulnerabilities from different vendors

How does single-vendor SASE improve security operations?

Single-vendor SASE also enables single-vendor agentic AI and a unified LLM to deliver automated, actionable alerts with clear response guidance for faster, more accurate investigations.

3. Improve SecOps efficiency

Using single-vendor SASE improves security operations efficiency.

• With separate vendor products SecOps teams are challenged to correlate network and security events
• Breach response is delayed with multiple systems and consoles
• Threat intelligence from multiple vendors is inconsistent and disjointed

4. Security event correlation

Using single-vendor SASE avoids the need for separate security event correlation.

• Investigations are faster and more accurate without the need to correlate events from two vendors
• Single-vendor agentic AI can give automated actionable alerts with clear response guidance with a single-vendor LLM

How does single-vendor SASE strengthen identity and segmentation?

Single-vendor SASE also enables comprehensive segmentation at device, application, and network levels – including blocking rogue IoT devices and enforcing Zero Trust principles across SSE gateways.

5. Enhanced adaptive identity

Using single-vendor SASE enhances adaptive identity.

• Two different vendors do not have the same view of users and they may need to reauthenticate at the SSE gateway
• SSE gateways configured to identify users by IP address may not have up to date assignments to map their security policies
• Identifying indicators of compromise like unrealistic travel becomes challenging

6. Segmentation

Using single-vendor SASE enables comprehensive segmentation.

• Enables device-level micro-segmentation action like blocking rogue IoT devices
• Enables application-level segmentation across flows through SSE gateways to enforce zero trust principles
• Enables network-level segmentation through transport and awareness of SGT tags

How does a unified architecture improve traffic steering and troubleshooting?

Single-vendor SASE also reduces troubleshooting time through unified network and security logs, removing manual investigations and the inefficiencies of working across multiple vendor support teams with conflicting perspectives.

7. Unified architecture

Using single-vendor SASE improves traffic steering using a unified architecture.

• No traffic hair-pinning with direct routing between the network and SSE gateways
• No extra hops between traffic forwarding and security processing nodes to add latency, loss or jitter
• No extra latency from backhauled flows between clients and their destination

8. Troubleshooting

Using single-vendor SASE reduces troubleshooting time and effort.

• Teams work with a consistent view of their environment with unified network and security logs and alerts
• Teams eliminate time-intensive manual investigations and guesswork
• They avoid challenges and inefficiencies that derive from working with multiple vendor support teams with different perspectives

How does single-vendor SASE improve forwarding and routing performance?

Native capabilities include traffic shaping, policing, acceleration, QoS, forward error correction, packet cloning, and multipath load balancing with SLA monitoring.

9. Forwarding performance

Using single-vendor SASE improves forwarding performance.

• It harnesses the full power of transport over SD-WAN in a way that manual IPsec tunnels do not provide, including traffic shaping, policing, acceleration, QoS, forward error correction, packet cloning, multipath load balancing with SLA monitoring , etc.
• Eliminates convoluted work-arounds to direct user traffic to SSE gateways with PAC files, routing tricks, and scripting

10. Resource routing

Using single-vendor SASE improves routing to target resources.

• SSE security processing gateways can dynamically learn routes and forward flows to data centers or hyperscalers
• Similar forwarding performance benefits over SD-WAN at the access leg that manual IPsec tunnels do not provide, including traffic shaping, policing, acceleration, QoS, forward error correction, packet cloning, multipath load balancing with SLA monitoring , etc.
