Cybersecurity involves both playing the good guy and the bad guy. Diving deep into advanced technologies and yet also going rogue in the Dark Web. Defining technical policies and also profiling attacker behavior. Security teams cannot be focused on just ticking boxes, they need to inhabit the attacker's mindset. This is where AEV comes in. AEV (Adversarial Exposure Validation) is an advanced offense technology that mimics how adversaries will attack your system, while providing remediation strategies. It lets you discover and address how your environment can be exploited and what the impact of the exploitation could be, in a dynamic and ongoing way. In this article, we'll share everything you need to know about AEV, and how your team can leverage it to build continuous resilience against attacks. What is AEV? According to the Gartner® Market Guide for Adversarial Exposure Validation (March 2025), AEV is defined as "technologies that deliver consistent, continuous, and automated ...

61% of security leaders reported suffering a breach due to failed or misconfigured controls over the past 12 months. This is despite having an average of 43 cybersecurity tools in place. This massive rate of security failure is clearly not a security investment problem. It is a configuration problem. Organizations are beginning to understand that a security control installed or deployed is not necessarily a security control configured to defend against real-world threats. The recent Gartner® Report , Reduce Threat Exposure With Security Controls Optimization, addresses the gap between intention and outcome. We feel it discusses a hard truth: without continuous validation and tuning, security tools deliver a false sense of, well, security. In this article, we'll take a deep dive into why control effectiveness should be the new benchmark for cybersecurity success, and how organizations can make this shift. The Myth of Tool Coverage Buying more tools has long been considered the k...

In a world of ever-expanding jargon, adding another FLA (Four-Letter Acronym) to your glossary might seem like the last thing you'd want to do. But if you are looking for ways to continuously reduce risk across your environment while making significant and consistent improvements to security posture, in our opinion, you probably want to consider establishing a  Continuous Threat Exposure Management (CTEM)  program.  CTEM is an approach to cyber risk management that combines attack simulation, risk prioritization, and remediation guidance in one coordinated process. The term Continuous Threat Exposure Management first appeared in the Gartner ® report, Implement a Continuous Threat Exposure Management Program (CTEM) (Gartner, 21 July 2022,). Since then, we have seen that organizations across the globe are seeing the benefits of this integrated, continual approach. Webinar: Why and How to Adopt the CTEM Framework XM Cyber is hosting a webinar featuring Gartner VP Ana...

Digital expansion inevitably increases the external attack surface, making you susceptible to cyberthreats. Threat actors increasingly exploit the vulnerabilities stemming from software and infrastructure exposed to the internet; this ironically includes security tools, particularly firewalls and VPNs, which give attackers direct network access to execute their attacks. In fact,  Gartner  identified attack surface expansion as a major trend to watch. So, it is not surprising that External Attack Surface Management (EASM) is a growing priority for organizations. But traditional castle-and-moat-based security architectures are ineffective at protecting enterprises against today's sophisticated attacks, which increasingly leverage AI and as-a-service models to maximize speed and damage. Zero trust security is the best way to minimize the attack surface, prevent compromise, eliminate lateral movement, and stop data loss. Register here  and join Apoorva Ravikrishnan, Senio...

The emergence of smart mobility services and applications has led to a sharp increase in the use of APIs in the automotive industry. However, this increased reliance on APIs has also made them one of the most common attack vectors. According to Gartner, APIs account for 90% of the web application attack surface areas.  With no surprise, similar trends are emerging also in the smart mobility space. A recent  Automotive and Smart Mobility Cybersecurity Report  by Upstream Security indicates that the automotive and smart mobility ecosystem has seen a 380% increase in API-based incidents in 2022, compared to 2021. Additionally, APIs accounted for 12% of total cyber incidents in 2022, up from only 2% in 2021.  When examining smart mobility applications and services, Upstream's threat intelligence team reported that black-hat actors were found to be behind 53% of incidents, indicating malicious intent as the driving force of the majority of API-related attacks. The imp...

As threats grow and attack surfaces get more complex, companies continue to struggle with the multitude of tools they utilize to handle endpoint security and management. This can leave gaps in an enterprise's ability to identify devices that are accessing the network and in ensuring that those devices are compliant with security policies. These gaps are often seen in outdated spreadsheets that are used to track and manage asset inventory, configurations, vulnerabilities, and more. Ultimately, this increases organizational risk while stifling efficiency and productivity. That's why unified security and endpoint management has gained ground, as noted in  Gartner's Hype Cycle for Endpoint Security, 2022 . As part of the market's need to gain a clearer, real-time picture of their devices and security posture, Syxsense launched its Enterprise platform last year to address the three key elements of endpoint management and security: vulnerabilities, patch, and compliance.
