8 Software-Defined Perimeter (SDP) Solutions for Small to Big Business

Using the right software-defined perimeter (SDP) solution can help you secure your organizational assets and infrastructure from attackers and unauthorized users.

Needless to say, the distributed workforce is prevailing across the globe, especially after the current pandemic. Users may connect to your organizational network from anywhere, using any device and connectivity, which can be insecure.

This is why it’s essential to have a stronger security approach like software-defined perimeter solutions instead of relying on a network-based approach.

Although traditional network architecture provides security by separating your network from the outside world using technologies like firewalls, routers, etc., for access controls, these methods are based on accessibility and visibility.

With blurred network perimeters in the current scenario with the arrival of cloud technologies, there are several entry points to infiltrate traditional access controls. Your external workforce and devices may carry several risks, enough to cause security breakdowns and render your traditional methods inadequate.

SDP solutions can help you encounter such risks by providing powerful, risk-free access controls.

In this article, we will discover a few things about SDPs, how they are helpful, and some of the best SDP solutions you can introduce in your organizational security toolkit.

Let’s begin!

What Are Software-Defined Perimeter Solutions (SDP)?

Software-defined perimeter (SDP) is a security approach to secure infrastructures, such as routers, servers, applications, and systems connected to the internet. It hides the systems hosted on the cloud and on-premises from attackers and third parties. And the solutions with SDP capabilities are known as software-defined perimeter solutions or SDP solutions.

This security approach aims to establish a network perimeter with the help of software rather than hardware. Businesses using an SDP solution essentially makes their infrastructure and systems invisible to keep them safe from unauthorized users and attackers.

SDP was developed in 2007 by the Defense Information System Agency (DISA). Further, the Cloud Security Alliance (CSA) became interested in the SDP concept and developed its framework. Interestingly, Google was among the first organizations to adopt the idea and create an SDP solution – GoogleBeyond Corp.

How Do SDP Solutions Work?

Instead of depending on traditional methods based on network security, SDP solutions help secure all the applications, users, and their connectivity. A software-defined perimeter solution creates a virtual perimeter or boundary surrounding a business’s assets and infrastructure at its network layer.

This perimeter separates the assets from external access-based controls restricting user privileges yet allowing network access. An SDP solution can authenticate both user identity and devices. It lets you access the assets only after evaluating the device state and validating user identity.

So, when the SDP solution has authenticated the device and the user, it creates a separate connection between the device and the server it tries accessing. The authenticated user is provided with a separate network connection and not connected to a wider network. No one other than the authenticated user can access this network and the approved services.

This strategy forms robust security for the organization implementing an SDP solution. It prevents attackers and unauthorized from infiltrating the network or accessing the assets.

Benefits of SDP Solutions for Your business?

With increasing cybersecurity risks, distributed workforce, and multiple device usage, strategies like software-defined perimeter (SDP) solutions seem to make good sense. Let’s understand how SDP solutions can be beneficial for your business.

Increased Internet Security

The internet comes with inherent risks from attackers who want to penetrate your network and systems to steal information, take over accounts, and pose various threats. The risk has become more grave after distributed workforce arrangements like work from home. Now, your employees, freelancers, or contractors might be working with you from around the world using different devices and networks, which could be insecure.

Hence, you can secure your network and organizational assets from malicious agents using an SDP solution. It helps you increase internet security within your organization for each user and device while preventing unauthorized users.

Safer Multi-Cloud Access

You can securely access multiple cloud services using just one environment using an SDP solution.

You may have been using services like Microsoft Office 365, AWS infrastructure services, a cloud development platform, cloud storage, and other services. They all need security, and an SDP solution is a great way to secure them. This will also help you start your Zero Trust security journey by securing every connection, device, and user irrespective of where they are located or hosted.

Faster Mergers and Acquisitions

Mergers and Acquisitions (M&A) with traditional methods can be very complex and time-consuming when converging networks, devices, IPs, and assets. Using an SDP solution will simplify this process and secure them with strict security policies that require proper authentication for each user and device. It will also cut down the time spent on settling the processes to get started quickly and run your operations.

Low Third-Party Risks

Often, organizations may give extra privileges to third-party users that they don’t need to fulfill their roles. If you don’t monitor access for your third-party users properly, it may create security loopholes for attackers.

But if you use an SDP solution, you can address this concern by giving required access to every user, including third-party users, enough to do their jobs. The authorized users can only access your network, applications, and assets they are allowed to. Hence, they won’t be able to see other assets or make changes to them. This significantly lowers security risks.

An Alternative to VPN

Using VPNs can sometimes be tedious, tough to manage, and invite security risks. VPN may offer encrypted access but may not allow you to access a certain network. This is why many organizations are looking for a better, safer alternative to VPNs, such as SDP solutions.

Apart from the above benefits, SDP solutions can also help you restrict wider network access so that users can only access specific services and prevent vulnerability and port scanning by attackers and malicious software. An SDP solution can support multiple devices, connect various systems, and isolate mission-critical data and apps for security.

So, if you want to introduce SDP in your organization, here are some of the best software-defined perimeter (SDP) solutions for small to big businesses.

Perimeter 81

Build a concrete wall around your network with Perimeter 81’s software-defined perimeter solution and replace VPN legacy. It can help you design a stronger and more flexible access policy book for device and user authentication.
