Breach and attack simulation (BAS): XM Cyber

Breach and attack simulation is an adversary emulation solution akin to manual pen testing or red teaming. Real-time alerts and visibility allow administrators take action across evolving infrastructure environments, from cloud to SD-WAN frameworks.

XM Cyber Platform

XM Cyber launched in 2016 and is a winner for its innovation in the breach and attack simulation arena. The Tel Aviv-based vendor focuses on cyber risk analytics and cloud security software to give network administrators more robust visibility into threats. Their platform, previously known as HaXM, offers continuous adversary emulation on-premises and in cloud environments. With remediation guidance, network administrators know how best to protect their most critical assets continuously.

Cloud access security broker (CASB): McAfee

Cloud access security brokers (CASB) are secure cloud gateways for monitoring and managing cloud-connected networks. Managing cloud network access and encryption for securing sensitive data, CASBs offer stronger visibility into software and device inventory.

McAfee MVISION Cloud

Just three years ago, McAfee acquired Skyhigh Networks and entered the CASB market. Since then, the McAfee MVISION Cloud solution offers agentless data loss prevention (DLP) to large enterprises. McAfee makes our top CASB list, and their progress in the developing space of Secure Access Service Edge (SASE) can’t go unmentioned. In 2020, McAfee MVISION Cloud topped the Gartner Magic Quadrant for CASBs, while being named for a fourth straight year.

Read more about this solution in our McAfee MVISION Cloud review.

Runner-up: Microsoft Cloud App Security (MCAS)

Similar to McAfee, Microsoft joined the CASB market via the acquisition of Adallom in 2015. Fit for organizations of all sizes, the Microsoft Cloud App Security (MCAS) solution can be purchased as a subscription separately or bundled with Microsoft’s portfolio of security add-ons. MCAS integrates smoothly for organizations leaning on Microsoft software tools. In a case study on MCAS, Forrester found a risk-adjusted ROI of over 150% within a few years of purchase.

Endpoint detection and response (EDR): Kaspersky

Endpoint detection and response is vulnerability management at user entry points, providing comprehensive security like IAM, NAC, and PAM technology. Other features include data loss prevention (DLP), patching, and application whitelisting.

Kaspersky EDR

Kaspersky has been dogged by ties to the Russian government to the point we felt obligated to inform readers of the best alternatives to Kaspersky. That said, no evidence of a connection exists, and the company has taken pains to distance itself from its Russian roots, including the rare step of allowing an independent review of its source code. With comprehensive visibility across endpoints, automatic defensive mechanisms, and built-in firewalls, the Kaspersky EDR is a global leader in making endpoint protection seamless. Larger organizations most targeted by advanced persistent threats (APTs) like enterprises and government agencies, financial services, energy, and telecommunications make up Kaspersky EDR’s clientele.

Read more about the solution in our comparative analysis of Kaspersky and Symantec.

Runner up: Trend Micro Vision One

Trend Micro is also a global leader in cybersecurity. Their EDR platform, Vision One, most recently detected 96% of attack steps in MITRE ATT&CK test results, behind only SentinelOne and Palo Alto Networks. The Trend Micro Vision One solution offers various features from machine learning and behavioral analysis to sandbox integration and phishing protection. As EDR platforms like Trend Micro move towards extended detection and response (XDR), attack vectors are gaining more attention beyond endpoints.

What’s great about both Kaspersky and Trend Micro is they offer great security at bargain prices, hence their presence on this list.

Network access control (NAC) is a dedicated policy management solution for configuring legitimate endpoints. Capable of integration with SIEM, NGFW, and more, NAC solutions can evaluate endpoints and validate access.

Cisco Identity Services Engine (ISE)

After a bundle of cybersecurity acquisitions in the 2010s, multinational networking vendor Cisco makes our list for a second time with its Identity Services Engine (ISE) solution. The Cisco ISE offers policy lifecycle management, identity profiling, guest access, network security health, and incident response. As the industry moves towards zero-trust frameworks, Cisco claims ISE can automate policy enforcement for sensitive network access control and segment IT and IT environments.

Read more about this solution in our Cisco Identity Services Engine (ISE) review.

Runner-up: ForeScout Modern NAC

Like Cisco, ForeScout approaches NAC with eyes on what’s in front of us: zero trust. ForeScout’s roots in network access date back to 2000, and the vendor is an industry thought leader in its own right, with recent findings like Project Memoria’s AMNESIA:33 report. Their emphasis on the “enterprise of things” points to ForeScout’s greatest strength – extending protection beyond legacy network points and into visitor devices, work-from-home devices, IoT, OT, smart devices, and more.

Your guide to enterprise network security products

What is enterprise network security?

Enterprise network security is a broad term covering a range of technologies, devices, and processes. Some experts define it simply as a set of rules and configurations that protects the integrity, confidentiality, and accessibility of data in an enterprise network. Achieving this goal involves deploying software and hardware technologies to limit vulnerabilities and quickly respond when confronted by security issues.

The goal of any security system is to stop as many attacks as possible while being alert to and capable of responding quickly to breaches. Because of the inevitability of successful cyberattacks, many users give higher marks to products that allow them to respond promptly and effectively to attacks, even though another product may be better at stopping most attacks from happening.

The importance of robust enterprise network security

Firewalls are often the first line of defense, but network security hardly stops there. Access control, threat intelligence, intrusion detection and prevention, data loss prevention, email security, endpoint security, and patch management all play a role in protecting the network and its data.

Because advanced persistent threats and insider threats are the most significant danger to corporate secrets, behavioral analytics – studying user behavior for signs of an active intruder – has become a critical component of network security.

Tying all that together are products like security information and event management (SIEM) systems, bringing all security and log data into a centralized console for easier detection and response.

Complete and total IT security isn’t possible. Hence, organizations need to mix and match those security technologies and provide the optimal security level for their organization within cost constraints. With the average cost of a data breach approaching $4 million according to IBM, any security solution will pay for itself and avert trouble.

Managing Personnel Fatigue

The complexity of both corporate systems and the attacks against them can make it hard to sort legitimate security events from ordinary activities. IT security personnel can get overwhelmed if they lack the necessary tools to make sense of the data. Solutions that can identify and prioritize the most critical threats while reducing false positives are essential for reducing stress on security staff.

Scaling To Network Size

Unlike the monolithic corporate computer systems of the past, most enterprise IT environments today consist of large, interconnected systems, servers, and mainframes supporting thousands of individual devices often connected via multiple wired and wireless networks.

From the mainframes to the individual devices, every single node presents a potential point of attack. As a result, the larger your system, the more surface area it exposes to hackers who can use its complexity to conceal intrusions, exploit potential backdoors, and remain undetected in the infrastructure.
