Today enterprises face monumental security challenges. The complexity and quantity of attacks are increasing dramatically, often resulting in compromised personal, enterprise and customer data; misappropriated intellectual property; damaged reputations; and lost productivity. At the same time, security has become more complex. Organizations are grappling with the BYOD (bring your own device) revolution and the explosion of personal devices connecting to the network. Personal smartphones and tablets slow network performance and productivity, and mobile applications such as social media and video streaming consume an enormous amount of bandwidth. In order to address these network security and productivity challenges, some organizations have chosen to compromise their security by turning off features to maintain network performance.

Now organizations can be both secure and productive without compromising network performance. Emerging network security appliances comprising next-generation firewall capability deliver a deeper-level network security that does not compromise performance. These products deliver world-class security and performance, while at the same time offering ease of use and high value.  This gives organizations industry-leading protection, performance and scalability with a high number of concurrent connections, low latency and high connections-per-second with no file size limitations.

Leading-Edge Threat Protection with Advanced Performance

Emerging network security appliance products provide organizations that range in scale from mid-sized networks to distributed enterprises and data centers with advanced threat prevention in a high-performance security platform. Network security appliances utilize innovative deep learning technologies to deliver the automated real-time breach detection and prevention organizations require.

Unlike legacy firewall and intrusion prevention technologies, a network security appliance looks at all traffic, regardless of port or protocol. It blocks advanced malware attacks with the high on-the-fly SSL decryption rates. Its authentication server integration efficiently enforces acceptable use policy through granular application controls for bandwidth management and enhanced productivity. Unlike antiquated, two-box solutions that do not share threat information, the network security appliance integrates firewall and IPS. This connected intelligence enforces policy decisions to intensify security effectiveness, while slashing management burdens and organizational risk.

Today’s network threats are highly evasive and increasingly difficult to identify using traditional detection methods. Staying ahead of sophisticated attacks requires a more modern approach that heavily leverages security intelligence in the cloud. Without cloud intelligence, gateway security solutions can’t keep pace with today’s complex threats. Network security appliance offerings typically integrate two advanced security technologies to deliver cutting-edge threat prevention that keeps your network one step ahead. Real-time memory inspection technology is commonly the service used to enhance cloud-based threat protection services and which proactively detects and blocks mass market, zero-day threats and unknown malware by inspecting directly in memory. Because of its real-time architecture, network security appliance threat protection is precise, minimizes false positives, and identifies and mitigates sophisticated attacks even when a malware is exposed for less than a hundred nanoseconds.

Network security appliances also offer a deep packet inspection technology which examines every byte of every packet, inspecting both inbound and outbound traffic on the firewall. By leveraging cloud intelligence in addition to on-box capabilities including intrusion prevention, anti-malware and web/URL filtering, network security appliances have the ability to block even the most insidious threats at the gateway.

Simplified deployment and ongoing management

Network security appliances tightly integrate key security, connectivity and adaptive technologies into a single, comprehensive solution. This includes wireless access points and WAN acceleration, both of which are automatically detected and provisioned by the managing next-generation firewall. Consolidating multiple capabilities eliminates the need to purchase and install point products that don’t always work well together. This reduces the effort it takes to deploy the solution into the network and configure it, saving both time and money.

Typically, cloud-based centralized management, reporting, licensing and analytics are monitored using an intuitive dashboard for managing all aspects of the network in real time, including critical security alerts. Together, the simplified deployment and setup (along with the ease of management) enable organizations to lower their total cost of ownership and realize a high return on investment (ROI).

Interface Masters Technologies’ embedded network appliances are scalable network security platforms capable of supporting physical or virtual stand-alone IPS as well as integrated IPS and NGFW deployment options. The Interface Masters appliances feature off-the-shelf server hardware technologies to enable a fully converged, NFV-based virtualized infrastructure designed to support high-performance and secure IPS services. The embedded appliance platform also includes foundational software and open interfaces for management and orchestration, simplifying operation and enabling easier integration. From a deployment perspective, the Interface Masters NFV Platform can be equipped to support IPS applications in enterprise, small-business or branch office environments.

Interface Masters supports a full-range of network hardware security options including FIPS 140-2 (cryptographic security, levels 1-4), tamper resistant switches capable of detecting all forms of physical intrusion, mechanical enclosure designs capable of preventing probing and internal component visibility, battery backed real-time clocks with 10ppm accuracy, and off-the-shelf Trusted Platform Module (TPM) ready devices. 

Interface Masters Technologies has for over 20 years been providing off-the-shelf innovative networking solutions with customization services to OEMs, Fortune 100 and startup companies.
