Network Infrastructure Visibility
Knowing the makeup of your constantly changing network, switches, routers, hubs, and wireless access points, is fundamental to making sure it is secure. Network Sentry provides a real-time view of your dynamic network infrastructure ensuring that you can detect and prevent any changes that would introduce risk.
Device Profiling and Fingerprinting
With the proliferation of personal and mobile computing devices in organizations, the diversity and the ownership of the devices is difficult to manage. Network Sentry helps to identify and classify each type of device on your network, identify if it is corporate issued or employee-owned, and identify the user on the device to enable role-based network access policies.
The average number of devices per user is on the rise. This phenomenon also increases the attack surface of your network. Ensuring the integrity of wired and wireless devices before they connect to your network minimizes the risk of vulnerabilities and the spread of exploits and malware. Network Sentry, with agentless, dissolvable agent, or a persistent agent, validates the endpoint’s configuration as it tries to join the network. If the configuration is not compliant (i.e. patch missing, outdated antivirus, jailbroken device) then connections can be prevented or users can be warned until the endpoints are remediated.
Segmenting a network and classifying data are two best practices for data protection. Network Sentry, with role-based access control policies, ensures the right users on the right devices gain access to the right set of network segments. Users on corporate issued devices, because they are centrally managed by IT, may have more access on corporate issued devices than personally owned devices.
Guest Management and Self-Registration
Managing the onboarding of guests and employee laptops, tablets, and smartphones to your network, can be a labor intensive and error-prone task. Network Sentry simplifies onboarding by streamlining registration processes. Onboarding of guests can be delegated to deputy onboarding administrators and, when appropriate, users can self-register their own devices shifting the workload from IT to the end users.
Configuring an endpoint such as a laptop, tablet, or smartphone, for wireless access can be a challenging task. Even with will documented steps for end users, the process can be error prone frustrating the end-user and the staff that take the support calls. Network Sentry’s EasyConnect feature allows organizations to immediately and securely connect personal or corporate issued wireless devices to your network. EasyConnect automatically sets device security configurations, encryption type and other critical security settings on the user’s device, automating the onboarding process and removing the challenge.
Bradford’s Network Sentry™ network access control solution integrates with IT infrastructure and correlates network, security, endpoint device, and user information to provide total visibility and control over every user and device accessing your network.
Easily integrated into existing network environments, Network Sentry’s out-of-band architecture leverages the inherent security capabilities of existing network equipment along with authentication and authorization technologies such as 802.1X, RADIUS and Active Directory for identity management. By leveraging existing technology investments, organizations can quickly add advanced visibility and security capabilities to their current networks and avoid the need for expensive forklift upgrades or the scalability and management challenges of adding in-line equipment.
Through an easy-to-use web interface, Network Sentry provides powerful administrative tools for managing network and security operations. Its inherent flexibility lets IT organizations gracefully evolve their security projects from initial trials to pilot rollouts to full deployments to ensure effective security policy implementations with minimal impact on user experience. Network Sentry can be deployed either on a dedicated hardware appliance, as a virtual appliance or “in the cloud” via SaaS (Security-as-a-Service). The same functionality is delivered in all deployment models ensuring that Network Sentry can adapt to the unique needs of any network environment.
THE BRADFORD DIFFERENCE
The flexible Network Sentry platform is the first network security offering that can automatically identify and profile all devices and all users on a network, providing complete visibility and control. Unlike vendor-specific network security products, Network Sentry provides a view across all brands of network equipment and connecting devices eliminating the network blind spots that can introduce risk.
Drawn from Bradford’s extensive experience delivering secure network access, first to educational institutions and then to organizations across all industries, Network Sentry has evolved to offer exactly what customers need:
- Advanced Policy Management
- Guest Access
- Device Profiling
- Secure Onboarding
- Endpoint Posture Assessment
- Centralized Management
- Investment Protection
Identify Who and What Is On Your Network
Network Sentry provides visibility of every user and every endpoint device that attempts to access the network on any wired or wireless connection. Because it is tightly integrated with the entire network environment, Network Sentry provides complete visibility across the network infrastructure, right down to individual switch ports, wireless access points, and even remote connections such as VPN. An easy-touse, web-based administrative interface features a highly-customizable “dashboard” view of vital network information, allowing administrators to “drill down” with a mouse click for more details.
- Centralized administration and reporting from one console
- Visibility of all network devices, users and endpoints
- Unique search/locate function to quickly find a device or user
ADVANCED POLICY MANAGEMENT
Provision and Enforce Granular Security Policies
Network Sentry allows custom network security policies to be created and enforced automatically and consistently throughout the network to protect critical data and IT assets, and to ensure compliance with internal policies as well as industry and government regulations.
- Identity-based policies provision access based on user identity (Employee, Guest, Contractor, etc.)
- Device-based policies provision access based on device identity and type (IP phone, Printer, Handheld, etc.)
- Endpoint compliance policies allow or prohibit access based on the endpoint security posture (Up-to-date OS, Patches, Anti-virus/Antispyware, etc.)
- Time-based policies provision access based on time of day, day of the week
- Location-based policies allow or prohibit access based on the connection point (wired port, wireless access point)
This is just a sample of security policies that can be managed with Network Sentry. Unique policies can be created and deployed to meet the specific needs of any organization.
Automate and Simplify Network Access for Guests
Network Sentry ensures secure network access for guest users, while simplifying and automating the creation and administration of guest accounts. Authorized sponsors can easily provision individual guest accounts as well as group accounts for meetings and conferences, removing the daily burden of guest account management from IT staff. Self registration capabilities further simplify the workflow, allowing guests to request network access “on the fly” with sponsor approvals and account setup processed automatically. Unique login credentials (username/password) can be delivered to guests via SMS text or email on their mobile devices.
Dynamically Identify and Classify All Endpoints
Network Sentry automatically discovers and profiles all endpoint devices and classifies them by type, greatly enhancing visibility of what is on the network and providing additional policy conditions for provisioning network access. Profiling criteria may include a combination of IP range, location, DHCP fingerprint, TCP or UDP ports, active (NMAP) and passive (p0f) fingerprinting, and vendor OUI. Device profiles can also help streamline IT workflow with automated delegation of management responsibilities by device type.
EASYCONNECT SECURE ONBOARDING
Automate 802.1X Endpoint Security Settings
For “BYOD” and guest network environments using 802.1X, Network Sentry’s EasyConnect feature simplifies the process of onboarding new devices by dynamically configuring security settings on Windows, Mac OS X, iOS and Android devices. In the event a device initially connects to an open (unsecure) wireless SSID, Network Sentry can automatically configure its security settings and transparently move the device to a secure SSID.
ENDPOINT POSTURE ASSESSMENT
Validate Security Posture and Remediate At-Risk Devices
The security posture of an endpoint is crucial in managing access policies. An endpoint can be known and authorized, yet still at risk – for example, if its operating system patch levels or anti-malware tools are not up to date, or if prohibited applications are installed. Network Sentry enables comprehensive endpoint scans for assessing endpoint “health” and ensuring compliance with security policies. Endpoint policies can be defined and validated by OS type (Windows, Mac OS X, Linux), and Network Sentry offers flexible options for endpoint posture assessment, including persistent and dissolvable agents as well as agentless directory-based scanning.
Remediation of non-compliant endpoints can be automated through integration with patch management systems or can be achieved by educating the end users on why they are non-compliant and/or forcing the endpoint to an isolated or limited-access VLAN. Instructions for achieving compliance can be delivered via a captive portal or displayed on the user’s desktop and access can be granted once the corrective actions have been taken.
Manage Security Functions through a Single Interface
Network Sentry empowers IT administrators with extensive management and control functionality. Features built into the existing infrastructure can be leveraged to secure the network. Control features can be accessed via the web-based administrative interface. For example, any user or device on the network can be easily located and identified with a few mouse clicks. Potential threats can be mitigated by isolating suspect users or at-risk devices, or by disabling their access completely.
In addition, control of the network environment is greatly simplified with Network Sentry and its ability to automate administrative tasks. For example, if an unknown device were to connect to a switch on the network, this event could trigger an automated alert to IT staff and the switch port could be automatically disabled or the device quarantined to protect the network.
A Solution to Meet Evolving Security Challenges
Network Sentry enables organizations to adapt to a wide range of business and technology challenges, and has been architected to allow security solutions to be rolled out in phases, addressing the most critical needs to start with and then phasing in additional capabilities as required. Start in “monitor only” mode for network-wide visibility. Then enforce basic “friend or foe” access control policies to secure the network. Next might be Guest access and “BYOD” security policies, followed by more advanced policy management across the network.
Leverage the Existing Network Infrastructure and Security Ecosystem
By integrating with the entire network and leveraging capabilities of the current network infrastructure, Network Sentry allows organizations to maximize the potential of existing IT investments. Network Sentry is architected to adapt to changing technology environments without requiring “forklift” upgrades, future-proofing today’s investment for years to come.
With an increasing mobile workforce comes a dynamic edge to today’s networks. The devices, once consistent and well–managed, are now diverse and can be owned by the employee. Network Sentry provides a deep understanding of the device type, its risk profile, and the user on the device. This information is typically not readily available to the security products that detect anomalies and identify the source as an IP address. The investigation cannot stop there. Network Sentry correlates the IP address to a device type and owner to provide the level of depth needed to truly investigate security anomalies. Network Sentry can also monitor, report, or block network access using the feed from traditional security solutions such as Security Information and Event Management (SIEM) and Intrusion Detection/Prevention Systems (IDS/IPS).
Network Sentry provides extensive integration with your network and security infrastructure, authentication and directory services, and endpoint security software.

Flexibility extends to the way in which Network Sentry can be deployed in the network -- either on hardware appliances, as a virtual appliance, or “in the cloud” via SaaS (Security-as-a-Service). The same functionality is delivered in all three deployment architectures, ensuring that Network Sentry can adapt to the unique needs of any network environment.
Network Sentry can be purchased on hardware appliances tailored to your specific network environment. Several versions are available, including a single stand-alone appliance as well as appliances that can support higher capacities by splitting functionality between two paired appliances – an Application Server and a Control Server. This allows for increased performance and load sharing of hardware functions. All appliances include hot-swappable dual power supplies for redundancy, including RAID 1 disk redundancy and support for optional high-availability hot-failover configurations for environments requiring the highest levels of system uptime.
Network Sentry can also be deployed as an application in VMware ESX and ESXi virtual server environments. Organizations can leverage existing server infrastructure investments and the benefits of virtualization, including reductions in capital and operating costs, improvements in power efficiency and space utilization, reductions in risk of server downtime and improvements in IT staff productivity.
Virtual appliance versions of Network Sentry are similar to the hardware appliance versions. Each version requires virtual server resources (CPU, memory, etc.) equivalent to those of the corresponding hardware appliance versions.
Network Sentry can also be deployed “in the cloud” via SaaS (Security-as-a-Service). With no hardware on premise, the solution has the same capabilities as the appliance and/or virtual solution that is deployed on premise. The service is offered via Bradford Networks or Managed Service Providers (MSPs) who have added Network Sentry to their portfolio of cloud-based offerings.
