SSPM vs CASB are similar solutions but differ in some aspects. You can use CASB to control your identities, permissions, and data encryption. However, SSPM is meant for security and data protection for SaaS apps on the cloud. A Cloud Access Security Broker (CASB) sits on-premises between the CSP (Cloud Service Provider) and the consumer. It can enforce policies by identifying risks and compliance issues present within your organization.
It is expected that the CASB market will reach USD 37.1 billion by 2031 at its quickest growth in regions like North America, Europe, Asia-Pacific, and LAMEA. SSPMs have far less setup time, with easier management in comparison to CASBs. However, they protect only SaaS technology stacks. In a 2023 SaaS implementation planning survey, 80% of companies agreed to the fact that they were planning to increase their adoption of SaaS SPM solutions.
In SSPM vs CASB, SSPM outclasses CASB in securing niche cloud-based apps. They also offer advanced API discovery, inventory management, and a single pane of glass for visibility into the SaaS landscape. Of course, these tools are capable of providing security coverage for apps that could not be covered with CASB solutions.
However, CASB’s market continues to surge as businesses are making investments in these tools. CASBs can be adopted into pipelines to solve various productivity challenges. They are used for collaboration, data storage, and fulfill other unique security requirements.
So how do you decide between CASB vs SSPM? We’ll answer that today.
What is SSPM?
SaaS apps streamline business processes and make it affordable to run daily operations.
It lets them not worry about constant upgrades, patches, and take care of maintenance.
But the downside is security. There are potential data privacy concerns, limited customization options, and a lack of specific features. SaaS Security Posture Management (SSPM) solutions can keep a constant eye on these apps and fix potential vulnerabilities.
SSPM tools can identify any misconfigurations with SaaS apps and provide a single-pane-of-glass visibility for all SaaS-related security risks. On a high level, it can also perform deep analysis and perform thorough validation of existing security benchmarks and checks.
What are the key features of SSPM?
SSPM solutions provide many key features that are as follows:
- SSPM solutions can continuously monitor and enforce security policies for SaaS cloud apps.
- SSPM tools can easily be integrated with customer support tools, workspace, dashboard, video conferencing platform, messaging apps, and any other set of integrated software solutions.
- You can execute built-in security checks and configure your SSPM for compliance with industry-specific standards such as HIPAA, PCI-DSS, and others.
- SSPM solutions help IT teams to better understand security risks and derive actionable insights. This single pane of glass view in a unified dashboard will give them all relevant information regarding security matters.
- Of the two, SSPM and CASB, SSPM appears to be more apt for businesses that want deeper visibility of user behaviors and probable vulnerabilities that are associated with SaaS applications.
- SSPM will encrypt both data in transit and at rest. Most SaaS providers offer built-in encryption services but many third-party tools offer proper encryption and support.
What is CASB?
CASB is only concerned with point-of-access monitoring and does not cover SaaS environments.CASB is all about control and acts as the gatekeeper of cloud services. It is a tool that enforces custom security policies and provides robust access controls.
What are the key features of CASB?
Here are the key features of CASB that can help boost cloud security posture:
- CASBs can combine multiple different security policies, including ones related to credentials mapping, malware detection, encryption, and more.
- CASB can ensure robust cloud app security for both authorized and unauthorized apps, also for managed and unmanaged devices.
- Organizations can detect unusual behaviors or anomalies in networks by using CASB tools. CASB tools specialize in thwarting ransomware attacks, rogue apps, and can safeguard compromised users from further escalations.
- Among SSPM vs CASB, CASB can identify threats found with increasing application usage and analyze them for automated remediation.
- Enterprises can enjoy strong data analytics when employing CASB tools. They can obtain a holistic security picture of their cloud activities and incorporate the necessary measures.
- CASBs can control access to users, cloud apps, services, and various other online activities. They can provide detailed insights regarding environmental usage and can, therefore, allow granular visibility.
CASB tools will help protect sensitive data like credit card numbers, personal information, health records, and social security numbers. These solutions will provide DLP technologies that can prevent the accidental sharing of unauthorized data.
3 Critical Differences between SSPM vs CASB
Here are some major differences between SSPM vs CASB:
#1 SSPM vs CASB: Security Policy Enforcement and Encryption
CASB can incorporate multiple types of security policy enforcement. For example, there are different types of security policies related to: single sign-on, authentication, device profiling, encryption, credential mapping, logging, alerting, tokenization, and malware detection/prevention. CASB can consolidate these security policies and implement them.
Enterprises can control access to corporate data at rest or in transit by using CASB tools. Nearly 50% of cloud data breaches happen due to failed audits. The increase in remote work practices organizations have to deal with growing sensitive data volumes. Cloud security is turned off by default for modern cloud services. CASB tools can encrypt such information and turn on security by default to keep them protected.
#2 SSPM vs CASB: Wide Range of Integrations
Each SaaS app is different and SSPM can integrate with a wide range of SaaS products. Some SaaS apps may act as an entry point to attackers which may pose certain risks. This can be prevented by taking advantage of other application integrations. SSPM can perform safety checks and guard against misconfigurations, unlike CASB. CASBs cannot cover all possible configurations and SaaS app settings. CASBs also suffer from a lack of adaptability to keeping SaaS apps secure, especially when features and functionalities evolve with their new releases.
Also, for custom integrations, CASBs require a proxy which will incur additional costs to organizations.
#3 SSPM vs CASB: Cost and Setup
In SSPM vs CASB, SSPM tools are far more affordable and easier to set up than CASBs. CASBs can only protect critical cloud apps and not the organization’s full SaaS tech stack. SSPMs also have the added benefit of being able to identify non-IdP users that sit outside the organization. They can identify user devices with poor security hygiene issues too.

- In SSPM vs CASB, Identity Access and Management (IAM) is not taken care of in SSPM. The right individuals may not have the right access to the right information at all times. SaaS SPM tools cannot manage user identities and their access to apps on their own. To enhance overall security posture, organizations will need to invest in dedicated IAM solutions with SSPM.
- SSPM cannot identify stored data on the cloud nor ensure its protection. You will need to pair SSPM with DLP (Data Loss Prevention) technology to prevent data breaches. Organizations need to learn how to set up appropriate security policies, define sensitive data access, and monitor data transactions.
In SSPM vs CASB, CASBs have their limits, and here are the ones you need to be aware of:
- CASBs cannot distinguish between app and user behaviors for cloud services. This is a big red flag in organizations and they only collect security data for analysis.
- Setting up CASBs for large enterprises is not easy; these solutions take considerable setup time and can be complex to configure and manage. Sometimes, organizations may need to use endpoint agents to redirect complex cloud traffic.
- Most CASBs focus on perimeter security and encrypt data at rest and in transit. But they can’t provide client-side encryption, code-level security, or take care of application vulnerabilities.
When to choose between SSPM vs CASB?
SSPM will help you build trust with your customers and maintain a stronger commitment to SaaS app security. It can help security teams detect SaaS application security events as they occur. It’s better than ad-hoc monitoring, manual testing, and most SSPM tools adopt an offensive security mindset.
