What Is Sdp Vs VPN

Don't Miss

How Does Sdp Relate To Zero Trust Network Access

What is a Software-Defined Perimeter (SDP)?

An SDP follows the Zero Trust Network Access, or ZTNA, approach to network security. It assumes that all users and connecting devices cannot be trusted.

This means users must go through the authentication process every time they access network resources, even if theyre already inside the companys network.

These measures may seem like overkill, but theyre becoming increasingly necessary. More employees work remotely now than ever before, with more than 26 million Americans working remotely at least part of the time according to the U.S. Bureau of Labor Statistics.

If a remote user is accessing a network with a device that has unpatched vulnerabilities, a hacker can exploit those weaknesses and gain access to sensitive information.

Zero Trust Network Access can prevent data breaches, which have long-lasting financial impacts. The average cost of a data breach is $3.86 million.

Deploying an SDP solution is one of the most reliable ways to secure network resources and prevent unauthorized access. Depending on how your companys infrastructure is set up, you can also consider using a VPN to secure and encrypt traffic to the network.

Is VPN Still Relevant

Over two decades ago VPN was thetechnology for providing secure remote access to the Internet. And at about the same time, the Motorola StarTAC was the mobile phone available in the market So yes, while VPN was once the best remote access solution for the business, it no longer is.

The modern digital business of today works differently and requires a new approach to remote access. An approach that enables capabilities such as granular security, global scalability, and optimized performance. Yet, VPN fails to address these capabilities.

  • VPN doesnt enable granular security policies. Instead, VPN provides users with a secure connection to the entire network, rather than to specific applications. This expands the attack surface and badly affects the enterprises security posture.
  • VPN was never designed with the purpose of delivering all users, at all locations, immediate and ongoing connectivity to enterprise applications. However, in a work-from-anywhere environment, this is exactly whats needed and VPNs inability to support global scalability results in slow response time and negative impact on employee productivity.
  • Optimized performance isnt supported by VPN as it relies on the unpredictable Internet. This means that for global access, IT needs to backhaul traffic to a VPN server in a datacenter and then to the cloud, adding latency to the VPN session and resulting in poor performance.

VPN Vs Sdp Which Is Reliable

The choice of whether to use a VPN or an SDP depends on you. Yes, you might still want to choose VPNs because theyve withstood the test of time and because many of them come with new and amazing security features for online security. But lets not forget that like SDPs, they also started shaky. The world may not know much about SDPs yet, but in due time, they might take over the whole cybersecurity realm.

And now that you know a lot about SDPs, you might want to take action. After all, its pretty obvious that the internet is becoming a place filled with risks and vulnerabilities. While there are reliable VPN solutions out there, SDPs offer you an added advantage of a completely safe network access.

Cybersecurity is constantly evolving, but the question is, are you willing to keep up?

Which Should I Use

There has been a major shift in the workplace with a large percentage of employees working remotely outside of the traditional office environment. With this trend comes an increasing concern regarding security, access, and scalability of providing todays global distributed workforce with secure remote access. The traditional methods of access, security, scale, and control via Virtual Private Networks are no longer sufficient to meet the demand and security needs of the enterprise. Companies are moving towards leveraging SDP technology to allow them to scale, secure, and enable the operational reach and access required for todays remote workers.

Who Sdp Is Better For

SDP vs. VPN: Whats the Difference?

Organizations move to an SDP solution when the infrastructure struggles to protect a perimeter-based security solution such as VPN technology. Because SDP provides continuous authentication, IT departments have more visibility of network traffic and activity. Better visibility became crucial as remote traffic grew during the pandemic.

The increase in remote workers resulting from stay-at-home orders also created a security crisis for many companies. With more access points and unsecured home networks, organizations’ attack surfaces expanded, giving hackers more opportunities to identify and exploit vulnerabilities. By deploying SDP, companies developed tighter authentication procedures and more restrictive access to digital resources.

The improved security eliminated known vulnerability targets such as VPNs and Remote Desktop Protocols . SDP also reduced the opportunities for exploiting cloud vulnerabilities as organizations moved to more cloud-based solutions. Its flexibility made it easier to manage personal devices and home networks used for work.

How Does Sdp Relate To Ztna

ZTNA is an approach to network security consisting of several security concepts, it is not a single principle and currently not one single solution, however, in the future, there will likely be vendors that do provide a complete suite. As outlined in Gartners Market Guide for ZTNA, there are two current forms with the favored deployment being Endpoint-Initiated based on the Cloud Security Alliances SDP architecture.

Comparing Sdp To Traditional VPN

One of the big advantages of SDP is that it offers the same user experience for those accessing resources remotely as it does for users within the confines of the office. And usually, it does it more securely than VPN in the process.

VPNs are designed to provide an encrypted communication tunnel through traditionally firewalled network boundaries to access on-premises resources. But they’re a notorious performance chokepoint for remote users, especially when tapping into cloud-based resources, and they usually provide very broad access to large swaths of the corporate network.

Some other key differences include the following:

How VPN works
VPN authorizes access based on IP address SDP grants access based on identity
VPN typically provides access to all of the applications and data within a broad network segment SDP only provides access to specific assets that users have been authorized to use to do their jobs
VPNs connect by listening for incoming connections SDP responds to outgoing connection requests, meaning the user never access the network itself, which remains hidden from attackers

Whereas the SDP operates the same regardless of the location of the user or the resource, and connections are made on a very granular basis so that users and devices only get limited access to a very specific set of network resources.

VPN vs SDP A Live Hack

With a clear understanding of software-defined perimeter and virtual private network, lets look at the key differences between both and how SDPs are the next generation of VPNs.

  • Isolated application access to any application
  • Makes applications invisible until a users identity has authorized and authenticated
  • Continuous risk assessment at the device, user, and application levels
  • Least-privilege access through IAM integration
  • Secure access for any application, cloud, or on-premise regardless of user location
  • Access before authentication
  • Network access is needed for access to applications
  • Open ports exposed to the internet
  • No device risk assessment
  • Difficult to enforce least-privilege access
  • Dynamically scales according to business needs
  • Infrastructure management outsourced to the service provider
  • Integrates with IAM, SIEM, and other parts of the technology stack
  • Heavily appliance-based
  • Inflexible infrastructure and static capacity
  • Administrative overhead of management
  • Susceptible to misconfiguration and dependent on the configuration of other technologies
User Experience
  • Consistent access across device types and platforms
  • Provides the same access experience for remote users and workers on-site
  • Efficiently handles network transitions and built for all device types
  • Distributed service edge allows for efficient routing to mitigate latency
  • Seamless authentication and SSO

Sdps Are Easier To Manage

Any organization that has just expanded and transitioned from having a centralized data center into multiple cloud deployments can attest how complex it is to manage VPNs. Not only do IT administrators need to configure VPN settings and firewall policies, they also need to synchronize it across different locations.

Unlike VPNs, SDPs are easier to manage. As a matter of fact, they offer a simpler administration and management process. It administrators can directly onboard and add a network resource to an SDP platform. They can also manage all settings and policies in the cloud. This means the need to sync and configure across various locations is avoided.

Sdp Vs VPN: What Are The Differences

SDPs may incorporate VPNs into their architecture to create secure network connections between user devices and the servers they need to access. However, SDPs are very different from VPNs. In some ways, they are more secure: while VPNs enable all connected users to access the entire network, SDPs do not share network connections. SDPs may also be easier to manage than VPNs, especially if internal users need multiple levels of access.

Managing several different levels of network access using VPNs involves deploying multiple VPNs. Suppose Bob works at Acme Inc. in accounting, Carol works in sales, and Alice works in engineering. Managing their access at the network level involves setting up three VPNs: 1) an accounting VPN to provide access to the accounting database, 2) a sales VPN for the customer database, and 3) an engineering VPN for the codebase. Not only is this difficult for IT to manage, it is also less secure: anyone who gains access to the accounting VPN, for instance, can now access the financial information of Acme Inc. If Bob accidentally gives his login credentials to Carol, then security is compromised â and IT may not even be aware of it.

It Is Time To Retire Your Legacy VPN And Move To A Software Defined Perimeter

For almost 20 years, organizations have depended on VPNs to enable secure remote access for remote employees or third parties. While VPNs have served us all well, it is time to evolve beyond them. They are showing their age, in that they do not fully address the security threats we all now face. In the new security landscape workers are often remote, threats are just as likely to be inside the perimeter as outside, and the applications and data are likely in the cloud. Given the changes required to adapt, your existing VPN vendor cannot evolve their technology to meet these new requirements. What is needed is not evolution, but an actual leap to a new approach A Software Defined Perimeter is that new approach.

The good news is that while SDP is a big leap in terms of the level of security, deploying it is a short hop. With a small investment in time, resources, and money, you can have SDP protecting everything your current VPN does, but better, as detailed, below. Given this new generation of secure access technology along with the recent increase in remote work, it is time for your organization to leverage the advantages of moving to SDP by migrating from your legacy VPN to SDP. Lets review the advantages.

Sdp Vs VPN: Authentication


An SDP takes a zero trust approach to authentication. The system authenticates each users identity and device every time they attempt to access network resources.

A VPN authenticates a user with their username and password, but it doesnt authenticate their device. This poses security risks if the connecting device is compromised.

Zero Trust Vs VPN Vs Sdp: Which One Should You Choose

Network and communication needs are rapidly changing and the number of sophisticated cyber security attacks is increasing. As a result, organizations are trying to find better cybersecurity solutions that will protect their networks, applications and information. Three of the most debated technologies are Zero Trust , VPNs, and SDP. This blog post will explain each one and when you should choose it for your organization.

Ztna Sdp Are On The Rise Vendor Count Triples

But the overall trend is away from VPNs. Matt Chisholm, Content Marketing Manager at NetMotion Software, expects that SDPs will eventually take over. But there are many factors that inhibit the instant switch to the newer technology.

The transition will not occur overnight as most organizations have on-premise applications, he said.

Meanwhile, the excitement over SDPs and their market potential is highlighted in the number of startups entering this space. The vendor count in SDP has grown from 10 to more than 30 in the past two years. And now, we see the big boys taking note. Some are developing their own SDP technology. Others are gobbling up the best and brightest among the SDP startups. Over the past year or two, Verizon has acquired Vidder SDP, OPSWAT has acquired Impulse, Symantec gained Luminate, and Proofpoint has acquired Meta Networks.

Covid Accelerates The Trend

SDP vs. Zero Trust vs. VPN: Comparing Network Security Technology

Having pushed many organizations further into the cloud than they anticipated, COVID-19 may have accelerated the trend from VPN to SDP. NetMotion numbers show that 70% of organizations are at least considering SDP adoption over the next year. The delaying factor is the extent of cloud adoption. Most have deployed more cloud resources of late, but few have gone all in. Only 4% of enterprises globally have fully migrated to the cloud, according to the survey.

While SDP is the latest and greatest, sluggish transition to the cloud is causing many enterprises to consider modernization of VPNs, firewalls, and secure web gateways as a more viable approach than changing over to SDP. An interim alternative under consideration by some is to migrate their VPNs to the cloud. By doing so, they make it easier to both implement an enterprise cloud strategy, as well as open the door to eventual implementation of SDP.

Zero-trust technologies and policies are another potential driver of SDP adoption. Zero trust has become something of a security buzzword in recent months. With the topic under discussion in board rooms, ZTNA/SDP projects could find themselves more likely to receive a green light.

VPNs Are Not That Flexible

At a certain level, a VPN can offer flexibility as it can be used to access different sites and connect to different data centers and virtual cloud networks. But it is worth noting that the connection options are often resource-intensive. Even worse, tapping into them drives up the costs. No organization would want that.

For Strong Network Security Many Vendors Say VPNs Don’t Cut It Anymore Enter Sdp And Zero

To create a secure tunnel from one point to another or to make resources invisible to outside threats may seem like scenarios that require magic in reality, they just need network security.

So begin the stories of VPNs, software-defined perimeter — or SDP — and zero-trust networks, three forms of corporate network security that present different approaches to security, with a shared goal of securing company resources. While VPNs have historically had a place in most network security plans, SDP and zero-trust networks are somewhat newer frameworks that aim to build off VPN capabilities and fill in the security gaps that VPNs miss. Still, VPNs have proven records of success in network security, while SDP and zero-trust models remain nascent.

Despite the differences between SDP vs. VPN vs. zero-trust networks, a shared goal for secure corporate networks ties the three technologies together, as does the increasing need for remote work support among organizations.

Sdp Moves Beyond Just Pretending That The Fiction Of A Hard Perimeter Still Exists

The increasing adoption of zero-trust security technologies by organizations of all sizes is an evolving trend. As organizations look to reduce risk and minimize their potential attack surface, having more points of control is often a key goal. Security professionals also typically recommend that organizations minimize the number of privileged users and grant access based on the principle of least privilege. Rather than just simply giving a VPN user full local access, system admins should restrict access based on policy and device authorization, which is a core attribute of the zero-trust model.

A well-architected zero-trust solution can also offer the potential benefit of less overhead, without the need for a physical appliance or client-side agents.
