I think recently with many people working from home, Cisco Umbrella has been very useful. For example, we can manage the device and the network when the employee is not working on the local host. Cisco Umbrella is very valuable for this kind of infrastructure.
It is fairly similar to other solutions. It has the capability for testing link connectivity, which is its unique feature from a control perspective.
Some of the best features are the SD-WAN platform for VMware and the NSX network virtualization.
There are plenty of features this solution provides and the most valuable would be the complete security protection we are receiving. We are provided with similar security that the Palo Alto AWS solution has. This includes features such as a firewall and machine learning AI.
The interface is good.
The feature that I like best is the GUI.
The division of Control Plane and Data Plane is most valuable. It can be deployed anywhere, and you can control it and configure it from anywhere. This is one of the good features of this solution.
The solution’s AJAX-VM provides constant reverse proxy uptime. It has been very positive for our security operations. When people are trying to access the SaaS solution, it protects us from downloading any of that data and experiencing any type of attacks
It's a pretty straightforward solution.
The WAN aggregation feature is the most valuable.
It's an easy-to-use product.
In terms of their compatibility with major cloud providers, in terms of their abilities, capabilities, and features, they exceed everyone's capabilities in the CASB market.
What is the SASE Model?
Existing technologies and network approaches no longer provide the access control and levels of security that organizations need. There is a necessity today for a new approach to network security, what with an increase in SaaS (software as a service) applications and remote users and the move of data and traffic to cloud services.
Secure Access Service Edge is a new approach to network security that combines software-defined wide area networking (SD-WAN) and VPN capabilities with cloud-native security functions like firewalls, CASB (cloud access security brokers), and zero-trust network access. It identifies devices and users, applies policy-based security, and then delivers secure access no matter where users, devices, or applications are located. SASE is an attractive option because it can be easily scaled and is billed based on usage.
Main Characteristics of the SASE Security Model
The SASE model has four main characteristics:
1. Identity-driven. The networking experience and the level of access are determined by the identity of the actual user and the resource, rather than simply by an IP address. The identity associated with the network connection drives the quality of service, the route selection, and the application risk-driven security controls. This approach allows companies to develop one set of security and networking policies for users regardless of location or device. This ultimately reduces operational overhead.
2. Cloud-native architecture. The architecture of SASE leverages key cloud capabilities, including adaptability, elasticity, self-maintenance, and self-healing, to provide a platform that is efficient, adaptable, and available anywhere.
3. Supports all edges. SASE creates one network for all of the company’s resources. For example, physical edges are supported by SD-WAN appliances while users on the go are connected through mobile clients and clientless browser access.
4. Globally distributed. The SASE cloud must be globally distributed in order to ensure the full security and networking capabilities are available everywhere and the best possible experience is delivered to all edges.
Benefits of the SASE security model include:
- Price: Instead of paying for multiple products, combining them into a single platform will reduce your costs as well as IT resources.
- Flexibility: Cloud-based infrastructure offers services such as web filtering, threat prevention, sandboxing, data loss prevention, credential theft prevention, DNS security, and next-generation firewall policies.
- Better performance: Cloud infrastructure allows you to easily connect to anywhere resources are located.
- Simplification: Minimizing the amount of security products your IT team needs to manage, update and maintain, will simplify your IT infrastructure, as will centralizing your security stack into a security service model that is cloud-based.
- Zero Trust: A SASE solution provides complete session protection, regardless of where users are connecting from.
- Data protection: Instituting data protection policies within a SASE framework helps to prevent abuse of sensitive data and/or unauthorized access.
- Threat prevention: A SASE solution provides more security and visibility.
1. The security, networking, and systems teams are fully siloed.
In this case, the network team manages and operates an SD-WAN with other network-centric systems, such as DDiS mitigation, DNS protection, and CDNs, to protect it. A remote site has one or more tunnels under the control of the network team, and then the security team has its own tunnels through which it manages the security portion. Therefore, multiple vendors are needed and as a result, additional money will have to be spent.
2. The security, networking, and systems teams are siloed but have agreed to manage a common infrastructure.
In this case, a uCPE (universal customer premises equipment) device at the remote site maintains role-based access control, enabling the cybersecurity and network teams to each manage their respective parts of a service that is integrated. This can get complicated at times, but at least saves money because only one vendor is required.
3. Choosing products.
If your IT teams will remain fully siloed, you will need at least two products: one (or more) for security and another one (or more) for networking. However, if your IT teams are siloed but agree to manage a common infrastructure, then these services can be combined into a single product.
4. Choosing NaaS (network as a service).
Some executives are looking at the possibility of an end-to-end service so that they don’t have to manage their WANs at all. In this NaaS model, the enterprise and the vendor’s client portal interface to set policies.
5. Integration and Interoperability.
Due to its scope, it is important that providers have features that are well-integrated, not ones that are cobbled together from pre-existing standalone point products. SASE endpoint agents need to be able to integrate with other agents to simplify deployments, with different kinds of cloud gateways, and with various kinds of proxies that are required in the overall solution.
6. Avoid DIY Solutions.
Rather than stringing together appliances and services on an ad hoc basis, it is preferable to adopt a true SASE solution that is provided by one or two vendors. This can prevent such issues as high latency, insufficient performance at scale, and a lack of control, network visibility, and necessary administrative tools. that cobble together a disjointed set of single-purpose appliances or services are destined to result in a solution with undesirable attributes. A well-engineered SASE solution should deliver simplicity, flexibility, and security that you wouldn’t otherwise have.
How Secure is SASE?
SASE is secured end-to-end and all communication across the platform is encrypted. Threat prevention capabilities such as firewalling, decryption, IPS, URL filtering and anti-malware are natively integrated into SASE and are also globally available to all connected edges.
