Zero Trust Dynamic Network Access Solutions
The first and last line of defense against cyberthreats—all in an innovative cloud-based solution. Zero Trust Dynamic Access can block user, app and data attacks, and gives trusted users secure access from virtually anywhere they connect to the network. Zero Trust Dynamic Access is a complete security service edge (SSE) solution built on an innovative distributed cloud architecture platform that combines non-physical cloud nodes and optional physical nodes across locations and devices, either on or off network, regardless of operating system used. Using a container-based cloud design, Zero Trust Dynamic Access helps protect users, devices and locations without the need for data backhaul or purchasing expensive appliances. Zero Trust Dynamic Access automatically connects approved and trusted resources by inspecting and authorizing each transaction between users and protected resources. Transactions are inspected for cloud access security broker (CASB), malware defense and data loss prevention to minimize the risks between authentication and sensitive data access. The platform continuously makes per-request access decisions using predetermined criteria and role-based access policies each time a transaction to sensitive apps occurs. Doing so helps reduce security risks by blocking access to sensitive data and apps as soon as a device is determined to be infected by malware or ransomware. Seamlessly transition from on-premises appliances to the cloud. Stay ahead of attacks by detecting threats quickly using content filtering and malware prevention measures. Limit hardware purchases and help control costs with a software-as-a-service subscription. Protect users, devices and locations, on or off premises, regardless of operating system.

Learn moreZTNA vs. VPN: Which Is Better for Enterprise Security? Business
We've got some great deals going on right now exclusively for our online customers... chat now to hear more! ZTNA vs. VPN: Which approach is better for enterprise security?,Author: Satta Sarmah Hightower,Critical business decisions about vs. approaches to enterprise security are currently driven by the and the increasing . These important trends mean that organizations can no longer rely on to effectively combat security threats. Here is the breakdown of ZTNA vs. VPN, including their differences and how ZTNA interacts with (SASE) to help you decide on the best security approach for your business. ZTNA vs. VPN: What's the difference?,Approach to security,ZTNA is an identity-driven security model that combines a range of security automation tools with adaptive security policies to restrict or grant access to an organization's network. It's anchored on the principle of least privilege, which means users only have access to the data and applications they need based on their roles. ZTNA assumes every user or device requesting access is a potential threat and enables context-aware, risk-based security decision-making that allows organizations to effectively protect their networks. VPN security encompasses an entirely different approach. VPNs allow employees or other authorized users to connect remotely, with firewall protection at each connection point or on the actual device. Data is encrypted and is transmitted through a virtual tunnel to securely connect a user to the internet from their respective location. VPNs use a central entry point to authenticate users and protect the perimeter, whereas and based on real-time risks in an organization's environment. Complexity,Organizations that use VPNs for remote access have to decide where to place VPN gateways for good performance and user experiences. But because VPNs rely on appliances, they're infrastructure-centric and limited in the capacity and number of entry points they can provide. VPNs can make sense for on-premise environments and flat networks, but most organizations now operate within a with hundreds, if not thousands, of endpoints connecting to their networks. VPNs also require organizations to adjust routing for new user groups and create firewall or access control list rules to provide authorization to applications. This adds complexity and risk, which requires multilayered security, robust security intelligence and automation, all of which ZTNA technologies encompass. Performance,Performance is another point of difference when you compare ZTNA vs. VPN. VPNs often have slower connections because they must backhaul traffic to a centralized enterprise data center. Based on the distance between a user's location and the server's location, the farther away the user, the slower the connection will be. This can delay user access to data-intensive work-from-home applications, like videoconferencing solutions and digital workspace platforms. In addition, Traditional VPNs aren't as scalable as ZTNA solutions, often requiring dedicated hardware (which can increase costs for organizations) that is time-consuming to deploy and not scalable when needs spike. VPN-based security also offers less visibility into connections than zero trust, especially if the connection is already infected with malware or other malicious software. VPNs provide some measure of protection if a user connects through their home network, happens to be on public Wi-Fi or if a company wants to facilitate secure access for employees at different branch offices. However, with the and the , the traditional castle-and-moat approach to security may not be the most effective approach for many organizations going forward. The perimeter now extends to employees' homes and from wherever they choose to work remotely, there is risk in trusting every user—even after they're granted access. To strengthen their security posture, organizations will need to restrict access and verify identities. ZTNA security and SASE,When comparing ZTNA vs. VPN, it's also useful to consider how ZTNA can be used as a critical component of emerging service-based security models, such as SASE. SASE is a service-based security architecture that when combined with (SD WAN) provides protection closer to the connection point, rather than backhauling traffic back to a centralized data center. Like ZTNA, SASE is an identity-driven security approach. However, rather than focusing narrowly on controlling access, SASE focuses more broadly on protecting the enterprise overall. ZTNA can keep bad actors from entering the gates and restrict their lateral movement if they do, while SASE integrates ZTNA security into a unified, cloud-delivered, service-based architecture to strengthen network security, optimize how traffic is routed and streamline network management. Together, SASE and ZTNA can strike the right balance between employee access and security to remove friction while effectively protecting the enterprise. Building a secure enterprise with ZTNA,As companies continue to adopt remote and hybrid work models and digitize their operations, they must ensure their security infrastructure is equipped to support this new way of working. VPNs were more effective during a time when threat actors weren't using sophisticated tools like artificial intelligence and machine learning to gain unauthorized access to systems and quickly move laterally through the network, wreaking havoc in their wake. The risks organizations face are great. ZTNA security is now a vital tool for them to manage a complex digital environment, increase their business agility and secure the enterprise in this new era of remote work.

Learn moreWhat Is zero trust and why does It matter Business
Author: Christopher Tozzi,In an era of leading organizations are increasingly moving beyond traditional perimeter-based security methods—for instance the (DoD) has announced a road map to move to a zero trust architecture by 2027. As zero trust is a major industry buzzword, it is helpful to understand the basics behind it and how to select a trusted partner to build your own road map to secure your network and devices. What is zero trust?,Zero trust (ZT) is the term for an evolving set of cybersecurity paradigms that move defenses from static, network-based perimeters to focus on users, assets, and resources.,Put another way, it means not trusting any entity on your network and disallowing communication between endpoints or other resources until you've vetted the entities and determined they're secure. A zero trust model requires continuous verification. Importantly, zero trust infrastructure doesn't just apply to anonymous or unidentified resources, such as external endpoints trying to connect to a server you run. ZT can also be applied to internal resources, like virtual servers your IT team created or a personal mobile device an employee brings onto your corporate network as part of a . Internal and external assets may contain security risks or vulnerabilities such as malware, so preventing them from interacting with other resources by default helps to minimize the chance of exposing your networks to attack. How zero trust works,At a high-level, here's how to put ZT into practice: Establish access controls or permission settings within your IT environment that until they've passed security checks. Exactly how you do that, however, depends on which assets exist on your network and which tools are available for securing them. Most modern IT infrastructure components, applications and mobile devices offer some type of access control framework you can use to enforce ZT, but the frameworks vary. For example, in an on-premises IT infrastructure, you'd typically use firewalls hosted within physical network switches or routers to control which devices can connect to which other devices. Alternatively, in a public cloud, you'd use the cloud provider's to manage connection permissions. Access control tools that reside locally on individual devices, such as Linux user, group and file permissions settings, can also play a role in achieving ZT. The importance of zero trust,Zero trust brings several key benefits to IT environments and organizations. ZT helps ensure security risks on one resource won't spread to others. If you don't allow entities to exchange data or share resources with other entities until you've scanned them for risks, you significantly reduce the chances that a vulnerability on one entity will impact others. Because ZT requires you to monitor for new entities on your network on a continuous basis, it helps ensure you always know what exists within your IT estate and the levels of access each entity has. By minimizing the ability of security risks to spread between devices or other endpoints, ZT reduces the amount of work IT engineers must perform responding to risks. Security incidents are easier and faster to address when they affect only one device, as compared to risks that have spread through the network by the time you identify them. ZT plays a pivotal role in protecting against risks that might be introduced through unsecured IT equipment use or through personal mobile devices employees use for work under BYOD policies. Thus, zero trust infrastructure allows organizations to support remote workers and allow BYOD while still enforcing strong security standards. Posture management enables enforcement of ZT by assessing the worthiness of these devices to interact on the network. Put simply, ZT helps organizations achieve higher security standards in a more efficient way. It also increases the flexibility of their workforces and networks by making it easier to connect a large number of devices without compromising on security. How to build a zero trust infrastructure,Zero trust is a concept, and there's no specific tool or singular process you can implement to enforce it within your infrastructure. However, a practical and efficient way to get started with ZT at your organization is to adopt the practices discussed in the . Those guidelines break the creation of zero trust infrastructure down into the following steps:Start by getting buy-in within your organization for zero trust as a principle. Educate stakeholders (such as managers, employees and customers) about the benefits of ZT and outline how it works. Next, identify which resources exist within your infrastructure—such as stationary computing devices, mobile computing devices and applications. This is important for understanding which tools you'll require for enforcing zero trust policies within each resource. Using access control tools that support each resource you need to protect, implement configurations that establish ZT. For example, on networking infrastructure, you can create firewall rules that block new endpoints from connecting to other endpoints until the new endpoints have passed security scans. Most infrastructures are constantly changing, and ZT strategies must change with them. To succeed with ZT over the long term, ensure you have the staff and tools necessary to update policies and processes on a continuous basis. The benefits of working with an experienced partner,As you work toward achieving zero trust within your IT infrastructure, you can benefit from working with an experienced partner. Verizon can share actionable insights from the analysis of 16,312 security incidents, of which 5,199 were confirmed breaches from the which helps guide organizations of all sizes to implement robust cyber security policies and solutions to better respond to threats.
