Together, we can reinvent your business
CASBs are just one component of a secure access service edge (SASE) or secure service edge (SSE) platform. These solutions focus on controlling and securing access to enterprise cloud services and SaaS applications, often by using principles of zero trust. Sample CASB vendors include Netskope, Palo Alto Networks, and Zscaler.
Comprehensive/Cloud Security Access Broker / Software Access Service Edge
In cybersecurity, “CASB” stands for “Cloud Access Security Broker,” which is a security tool that acts as an intermediary between cloud service providers and users, enforcing an organization’s security policies on cloud applications and ensuring data protection by monitoring user activity, managing access controls, and detecting potential threats across various cloud services.
Key points about CASB:
- Function:
Monitors user access to cloud applications, identifies suspicious behavior, and enforces security policies like data encryption and access controls to prevent data leaks and unauthorized access.
- Visibility:
Provides insight into cloud application usage, allowing organizations to identify “shadow IT” (unapproved cloud applications used by employees).
- Compliance:
Helps organizations comply with data privacy regulations by monitoring data usage and enforcing appropriate security measures.
- Deployment options:Can be deployed on-premises, in the cloud, or as a hybrid solution.
In cybersecurity, “SASE” stands for “Secure Access Service Edge,” which refers to a cloud-based framework that combines network connectivity features like SD-WAN (Software-Defined Wide Area Network) with various cloud-native security functions like firewalls, secure web gateways, and Zero Trust Network Access (ZTNA), delivering a unified platform to securely connect users and devices to applications regardless of their location.
- Unified approach:
SASE integrates networking and security capabilities into a single service, eliminating the need for separate appliances and simplifying management.
- Cloud-based delivery:
All security functions are delivered as a service from the cloud, allowing for scalability and flexibility.
- Components of SASE:
Includes SD-WAN, Secure Web Gateway (SWG), Cloud Access Security Broker (CASB), Firewall-as-a-Service (FWaaS), and ZTNA.
- Benefits:Improved security posture, consistent policy enforcement across locations, better user experience for remote workers, and reduced complexity.
Gartner defines single-vendor secure access service edge (SASE) offerings as those that deliver multiple converged-network and security-as-a-service capabilities, such as software-defined wide-area network (SD-WAN), secure web gateway (SWG), cloud access security broker (CASB), network firewalling and zero trust network access (ZTNA).
These offerings use a cloud-centric architecture and are delivered by one vendor. SASE securely connects users and devices with applications. It supports branch office, remote worker and on-premises general internet security, private application access and cloud service consumption use cases.
Why Choose Access Broker / SASE
- Proactive defense against emerging threats.
- Tailored solutions that align with your goals and industry.
- Increased organizational resilience and readiness.
- Support for achieving and maintaining regulatory compliance.
Our Access Broker / SASE Process
SASE Adoption Patterns
- Single-vendor offering
- A dual-vendor offering that is an explicit pairing of two vendors (typically one for network services and one for security services)
- Managed SASE
CASB
- The importance of real-time visibility and consistent policy enforcement to cloud data protection.
- Why adaptive data protection that extends into unmanaged devices and applications is critical to securing hybrid work.
- How CASBs serve as cloud-native DLP solutions for multi-cloud environments.

Uncovering Gaps and Vulnerabilities
- Buyers are increasingly preferring unified offerings. This includes a single management console, agent, policy engine underpinned by a single data lake. Further, they desire simplified and unified pricing for the offering.
- Buyers expect worldwide POP coverage that matches their enterprise requirements. Further, buyers are increasingly demanding more options for data and cloud sovereignty, including where traffic is routed, where it is inspected and where logs are stored. In some use cases, buyers are asking for local SASE delivery options, where inspection and logs can be kept local to the customer under their control.
- Digital experience monitoring has moved from an optional feature in 2023 to an expected capability in 2024, to improve troubleshooting and reduce mean time to detect/resolve issues.
- ZTNA is in the early stages of transitioning from being only for remote and mobile users, to an expected capability for users regardless of location (referred to as Universal ZTNA) — even when the user is located in campus or branch locations.
- Coffee shop networking — With hybrid work and the increasing mobile workforce, we see the increasing desire for coffee shop networking use cases where a user can plug in regardless of location and have the “same” experience.
Crafting a Tailored Security Strategy
Digital transformation over the past decade has shifted the network perimeter from the data center to the cloud. Today, the network edge extends even further, to the thousands of cloud environments operated by your SaaS providers—and to every remote employee and contractor who accesses those environments over the internet.
Cloud access service brokers (CASBs), cloud security gateways (CSGs), and secure web gateways (SWGs) emerged to manage and secure traffic and data between end users on a corporate network and the internet, cloud services, and SaaS applications. But, maintaining this network perimeter becomes increasingly untenable as SaaS use sprawls beyond a handful of key enterprise SaaS applications and as remote and hybrid workers connect directly to new and unknown SaaS applications off network and on personal devices. It’s no longer feasible to force all of your workforce’s internet traffic through this sieve.
This approach of trying to separate the good internet from the bad at an ever-changing network edge and forcing all user traffic through it is like trying to dam an ocean.
