Cloud Access Security Broker (CASB) eliminates cloud security issues by delivering a single solution to secure sensitive customer information across all cloud or on-prem applications. CASB acts as a gatekeeper, allowing organizations to extend the reach of their security policies beyond their own infrastructure. Cloud Access Brokers enforce a number of different security access controls, including encryption and device profiling. CASBs are particularly useful in organizations with shadow IT operations or liberal security policies that allow operating units to procure and manage their own cloud resources.

CASB Vendor Overview


Symantec Corporation is a global leader in cybersecurity. The company provides cybersecurity products, services and solutions to more than 350,000 organizations and 50 million individuals worldwide. The Integrated Cyber Defense Platform helps enterprise, business and government customers unify cloud and on-premises security to protect against threats and safeguard information across every control point and attack vector.

Symantec’s Blue Coat acquisition in 2016 turned out to be a success as their Elastica CASB solution CloudSOC moved Symantec beyond its legacy antivirus business. CASB revenues for Symantec in 2018 accounted for an estimated $315 million, which represented only 6.5% of its 2018 revenue. Just for comparison the overall revenue increased 20.28% from 2017, while CASB revenue showed a significant 44.8% growth. 

Symantec’s CASB solution, CloudSOC provides real-time traffic analysis of granular user activities, machine learning based threat detection, content classification for compliance and enforcement of data governance and account activity based security policies.

In February 2019, Symantec acquired Luminate Security, a privately held company with pioneering Software Defined Perimeter technology. Luminate’s Secure Access Cloud technology further extends the power of Symantec’s Integrated Cyber Defense Platform to users as they access workloads and applications regardless of where those workloads are deployed or what infrastructure they are accessed through.

The acquisition of Luminate continues Symantec’s strategy of acquiring and building best-of-breed security across its portfolio, with a particular focus on “born in the cloud, for the cloud” innovations. Symantec made first-mover acquisitions in CASB (cloud access security broker) and web isolation technologies and has delivered a broad set of cloud innovations and integrations across its entire portfolio.


Microsoft CASB solution is based on the Adallom Cloud Access Security Broker which was acquired in 2015. The product (Microsoft Cloud Application Security (MCAS)) is now integrated with other Microsoft solutions and forms part of Microsoft Enterprise Mobility + Security suite. The suite includes MCAS, Azure Active Directory, Azure Information Protection, Advanced Threat Protection, Advanced Threat Analytics, and Intune. 

Thanks to the native integration with other Microsoft products, it is used by many Microsoft customers. This perhaps gives the Microsoft CASB product a somewhat captive audience. In the end, features that touch each of the four pillars of CASB contribute to growth of  Microsoft Cloud App Security (MCAS). 


Forcepoint was formed in 2016 as a combination of Raytheon Cyber Products, Websense and Stonesoft organizations. The next year, it acquired the Skyfence CASB product and business from Imperva. Forcepoint enables better decision-making and more efficient security at the human point for more than 20,000 government organizations and enterprises worldwide with the help of the company’s security-based technologies. Forcepoint CASB has a worldwide presence with 50+ data center locations.

Forcepoint CASB provides visibility and control over both sanctioned and unsanctioned cloud apps. It also extends traditional cloud app discovery information by providing details on risk factors that are unique to the organization. These include visibility into dormant accounts, orphaned accounts and external accounts that present a variety of security risks.

Cisco Systems

In 2016, Cisco Systems acquired CloudLock. Cisco Cloudlock CASB platform integrates with other Cisco products and Secure Web Gateway technologies to defend against cyber-threats and implement security control across on-premises and cloud environments. Now it is part of a larger offering by the company called Umbrella. Besides Umbrella and Cloudlock, the offering includes Cisco Stealthwatch that helps to identify threat activity in public cloud infrastructure. 

The approximate number of  CloudLock customers is 700. This is a notable number for a product in the market which is fairly new and its target market remains enterprises with more than 1,000 employees.  

Cisco Cloudlock is a cloud-native cloud access security broker (CASB), the solution uses advanced machine learning algorithms to detect anomalies based on multiple factors. The simple pricing model, which is appealing to the clients, is based on number of applications and  number of users.  

McAfee MVISION Cloud

McAfee provides advanced security solutions to consumers, small and large businesses, enterprises, and governments. Security technologies from McAfee use a unique, predictive capability that is powered by McAfee Global Threat Intelligence, which enables home users and businesses to stay one step ahead of the next wave of, viruses, malware, and other online threats.

Recently, McAfee stepped up its push into the CASB market with the acquisition of Skyhigh Networks, which already had a strong customer base. Since the product is selling under the McAfee MVISION Cloud. McAfee Security Cloud was one of the first CASB products to raise awareness of shadow IT. Over time, the product expanded to provide thorough coverage of all four CASB pillars across a broad range of cloud services and now includes significant CSPM capabilities.  

In August 2019, McAfee acquired NanoSec, a multi-cloud, zero-trust application and security platform. The acquisition will enable organizations to improve governance and compliance and to reduce risk of their cloud and container deployments. NanoSec will strengthen the container security capabilities of McAfee MVISION Cloud and MVISION Server Protection products, giving its customers the ability to speed up application delivery while enhancing governance, compliance and security of their hybrid, multi-cloud deployments. NanoSec’s security capabilities will be applied to applications and workloads deployed in containers and Kubernetes and will be integrated into McAfee MVISION Cloud and MVISION Server Protection offerings.


In September 2016 Oracle acquired Palerra to enter into the CASB market. Since then Oracle has invested significantly in Oracle CASB Cloud Service, which was formerly called Palerra LORIC, by adding DLP and malware scanning, forward and reverse proxy deployment topologies, in conjunction with strong integration with Oracle’s Identity SOC that was an early entrant into this market and has a mature product with a strong and still growing user base. 

The user behavior analytics features in Oracle CASB incorporate data from access and in-application activity, support threat intelligence feeds, and provide threat modeling to assist with threat detection. Oracle CASB offers features that allow organizations to centrally control the native security configurations of SaaS applications and IaaS consoles. Oracle CASB is delivered as SaaS or sold through a managed security service provider.

Palo Alto Networks

Palo Alto Networks acquired CirroSecure in 2015, which was later launched as Aperture after integration into the Palo Alto Networks Security Operating Platform which added to the Palo Alto Networks Next-Generation Security Platform. Their platform’s CASB capabilities were extended in 2017 to include forward and reverse proxy CASB capabilities through its GlobalProtect cloud service.

The intended market for Aperture is existing Palo Alto Networks customers seeking cloud visibility and governance not available through Palo Alto Networks’ firewall alone. For Shadow IT Palo Alto Networks GlobalProtect cloud service and Next-Generation Firewall provide inline capabilities to detect, monitor and report on access to and risk of a range of external cloud services and applications. Aperture extends these capabilities via SaaS provider APIs to provide visibility and enforcement across all user, folder and file activity for sanctioned cloud apps. 


In late 2016 Proofpoint acquired FireLayers, an Israeli company with a solid CASB product, enriching the Proofpoint Nexus platform. After the acquisition, Proofpoint continued to evolve the product, adding capabilities for improved DLP, advanced threat detection, threat intelligence, and built-in two-factor authentication.

Proofpoint has a large installed base for its email security product, the target market for Proofpoint’s CASB is as an add-on for its installed base plus net new customers. The CASB provides insight into cloud usage at global, app, and user level.

In May 2019, Proofpoint acquired Meta Networks, an innovator in zero trust network access (ZTNA). With this acquisition, Proofpoint will strengthen its cloud-based architecture and people-centric security platform, enabling customers to better protect their people and the applications and data they access beyond the traditional perimeter. Proofpoint intends to integrate Meta Networks’ ZTNA technology with its cloud access security broker (CASB) and web isolation product lines to offer customers a comprehensive cloud access and security platform.

Later in November 2019, Proofpoint acquired ObserveIT, the insider threat management platform. With this acquisition, Proofpoint will extend its data loss prevention (DLP) capabilities with endpoint joining email, CASB, and data-at-rest to form an enhanced enterprise DLP offering.

CipherCloud Cloud Security Broker (CSB)

CipherCloud was founded in 2010 with a focus on enabling enterprises in a wide range of private and public sectors to secure their data and adopt the use of cloud services with confidence and compliance.
