The Perfect Recipe for Endpoint Security Calls for Privilege Control Today's most effective ransomware attacks don't require malware; they require a login. Modern threat actors don't need to break in. They can leverage legitimate identities and their privileges to gain a foothold, then continue to capitalize on them, moving laterally to probe for more opportunities and manipulate vulnerabilities and exploits to spread ransomware and spyware. A vulnerable identity or account tied to an endpoint can quickly become an attacker's ticket to your most valuable assets and controls.  With legitimate identities being used as the initial foothold in more attacks, we're seeing less 'anomalous' activity and far more seemingly normal actions performed by a trusted, privileged user. And attackers are keenly aware of how easily they can 'hide' behind these legitimate user accounts.  This is why Endpoint Detection and Response (EDR) is really only one piece of the endpoint protection puzz...

When generative AI tools became widely available in late 2022, it wasn't just technologists who paid attention. Employees across all industries immediately recognized the potential of generative AI to boost productivity, streamline communication and accelerate work. Like so many waves of consumer-first IT innovation before it—file sharing, cloud storage and collaboration platforms—AI landed in the enterprise not through official channels, but through the hands of employees eager to work smarter. Faced with the risk of sensitive data being fed into public AI interfaces, many organizations responded with urgency and force: They blocked access. While understandable as an initial defensive measure, blocking public AI apps is not a long-term strategy—it's a stopgap. And in most cases, it's not even effective. Shadow AI: The Unseen Risk The Zscaler ThreatLabz team has been tracking AI and machine learning (ML) traffic across enterprises, and the numbers tell a compelling story. In 2024 ...

With every credential breach that hits the news, CISOs and security professionals continually reach the same conclusion: passwords are insecure, and we should abandon them in favor of less risky authentication factors. But, secure or not, passwords are stubborn. The 2025 Verizon DBIR rated the likelihood of this being the year we finally eliminate passwords as being on par with "this being the year of the Linux desktop."  Any IT or security pro who has had to explain passkeys to their coworkers can tell you that 2025 isn't going to be the year we do away with passwords. Frankly, that year's not likely to come any time soon. Even if it were technically feasible (it often isn't) to transition every single login at a company to passkeys or biometrics, that would take years of concentrated effort. In the meantime, security leaders can't afford to sit on their hands and ignore the credential risks currently facing their company.  We need a new approach to thinking about secur...

Reachability has quickly become one of the latest buzzwords in cybersecurity, but every vendor means something slightly different by the term. In part one of this series, I argued that reachability is really about only showing exploitable vulnerabilities. In part two , I compared runtime and static reachability to determine that if the goal of reachability analysis is to only fix exploitable vulnerabilities, only runtime reachability will get us there. The final question to address is, "Which type of runtime reachability is the right kind?" In 2025, almost every vendor uses the term reachability, alongside a nifty funnel showing your vulnerability count going down, but vendors almost always mean different things by the term. In this article, we'll explore the complexity of reachability types, and how while there's no silver bullet, function level reachability for vulnerabilities is the best overall answer to the problem. Flavors of Runtime Reachability All excalidraws are availab...

Your identity environment holds the keys to your most critical data in the form of privileged accounts. Industry consolidation and a desire for company growth both often lead to mergers or acquisitions which, if not managed closely, can wreak havoc on an identity landscape. Mergers of identity environments create a glut of identities and identity accounts to manage, some of which may be redundant. They also introduce new 3rd parties, contractors and non-human identities like service accounts, bots etc.... into the equation. In addition, a merger or acquisition could hybridize the identity landscape, adding Cloud applications to on-prem resources, and vice versa. All of this increases the attack surface if not managed properly. As the two companies determine how to best work together, there is a level of uncertainty that can result in temporary measures as a stop-gap. Temporary access is often granted to provide employee, contractor and third party access to applications and privile...

Sub: GenAI is here to stay. The organizations that thrive will be those that understand its risks, implement the right safeguards, and empower their employees to harness it safely and responsibly. For many people, generative AI (GenAI) began as personal experimentation in homes and on personal devices. Now, however, AI has become deeply ingrained in workplace habits, creating productivity gains, but also exposing organizations to significant security gaps. Sensitive company data, inadvertently or otherwise, regularly finds its way into public AI systems, leaving IT and cybersecurity leaders scrambling to respond. Once proprietary data is processed by a public AI tool, it may become part of the model's training data, serving other users down the line. For example, in March 2023, a multinational electronics manufacturer was reported to have experienced several incidents of employees entering confidential data, including product source code, into ChatGPT. Generative AI applications, su...

Compliance is often treated as a paper exercise, something to tolerate, check off and forget. But in a threat landscape shaped by ransomware-as-a-service, AI-augmented phishing campaigns, and supply chain breaches, delaying compliance doesn't just create business and operational friction. It creates risk.  When compliance is layered late, organizations face mounting costs: duplicated controls, misaligned security priorities, reactive remediation efforts, and worst of all, security blind spots that attackers can exploit. Treating compliance as an afterthought is a gamble.  In this post, we highlight the real cost of sidelining compliance and why embedding compliance into your security strategy from the start is not just good hygiene, it's essential engineering.  Security and Compliance: Not Opposites, but Allies It's easy to think of security as "protecting" and compliance as "documenting". But that split is artificial. Frameworks like ISO/IEC 27001, NIST CSF, PCI ...

There's a war raging in the heart of every developer. On one side, you have the id: the impulse-driven creative force that wants to code at the speed of thought and would prefer to deploy first and ask questions later. On the other side, there's the superego, which wants to test every line of code and would push a release by a month if it meant catching one extra bug.  Experienced developers know how to act as a referee between these two forces and find the right balance between speed and security. But inexperienced or overworked devs often put their id in the driver's seat, which leads (among other things) to accidentally leaking developer secrets. These secrets include things like API and SSH keys, unencrypted credentials, and authentication tokens. Calling developer secrets "the keys to the kingdom" is something of a cliche, but it's tough to think of another phrase that accurately captures the unique power of this data. Unfortunately, the people who most appreciate the pow...

For businesses, compliance with regulations can often appear to be restrictive, and costly and reduce the speed of business. It's still necessary to create an environment that protects not only internal data but also external constituents like partners and customers. Highly regulated industries, such as healthcare and finance, are often faced with a variety of regulations that vary by geography and can carry steep penalties and consequences for noncompliance. Most companies struggle to comply with regulations. In fact, Business Wire estimates that " 71% of companies could potentially fail a cyber audit , which often includes identity management aspects".   What are some key compliance challenges your business may face?  Errors and inconsistencies resulting from repetitive manual processes Complex, evolving regulations that make compliance challenging Siloed environments and processes, often involving incompatible tools, or processes that do not match execution Difficu...

With thousands of endpoints, cloud instances, remote users, and third-party integrations, securing the enterprise has become a massive target. Each change in the IT environment - whether driven by digital transformation, M&A activity, or routine system updates - creates new opportunities for adversaries to leverage. Yet, the network is the backbone of business operations. It must always be available to support production, collaboration, and growth.  In this article, we'll explore the specific challenges large enterprises face when validating their security posture and how leading security teams are evolving their testing strategies to match the scale, speed, and sophistication of large, multi-faceted IT networks.  The Challenges of Validating Enterprise Network Security Enormous attack surface - In large enterprises, the attack surface spans countless assets across on-prem, cloud, and hybrid environments, making comprehensive security validation incredibly complex.
