Background for this topic.
Secure access service edge (SASE) is an architecture that delivers network connectivity and security controls from cloud points of presence. It commonly combines SD-WAN with secure web gateways, firewall-as-a-service, cloud access security broker functions, and zero-trust network access. Requests are evaluated using identity, device posture, application, and other context rather than trusting a user solely because they are on a corporate network.
SASE concentrates enforcement and visibility in identity systems, policy engines, connectors, and provider infrastructure. An overprivileged administrator, compromised identity, incorrect access rule, or exposed connector can therefore permit broader access or bypass inspection; TLS inspection and centralized logging also create privacy and data-retention obligations. Mitigate these risks with phishing-resistant MFA, separate and least-privileged administrative roles, tightly scoped application-level access, tested policy changes, continuous connector and device-posture validation, and independent monitoring of administrative and access logs. Validate provider isolation, outage behavior, logging retention, and incident-support processes before consolidating critical controls.

For years, routing traffic through cloud proxies was good enough. Then work moved to the browser, AI entered the workflow, and the inspection model stopped keeping up
Cato CTRL (Cyber Threats Research Lab) has released its Q2 2024 Cato CTRL SASE Threat Report. The report highlights critical findings based on the analysis of a staggering 1.38 trillion network flows from more than 2,500 of Cato’s global customers, between April and June 2024
Threat actors are evolving, yet Cyber Threat Intelligence (CTI) remains confined to each isolated point solution. Organizations require a holistic analysis across external data, inbound and outbound threats and network activity. This will enable evaluating the true state of cybersecurity in the enterprise
As SaaS applications dominate the business landscape, organizations need optimized network speed and robust security measures. Many of them have been turning to SASE, a product category that offers cloud-based network protection while enhancing network infrastructure performance
Being a CISO is a balancing act: ensuring organizations are secure without compromising users’ productivity. This requires taking multiple elements into consideration, like cost, complexity, performance and user experience. CISOs around the globe use Cato SSE 360, as part of the Cato SASE Cloud platform to balance these factors without compromise
Companies are engaged in a seemingly endless cat-and-mouse game when it comes to cybersecurity and cyber threats. As organizations put up one defensive block after another, malicious actors kick their game up a notch to get around those blocks. Part of the challenge is to coordinate the defensive abilities of disparate security tools, even as organizations have limited resources and a dearth of
