SASE Vs CASB – Enterprises looking to secure cloud services have two options when it comes to choosing a CASB: standalone and full integration/optimization solutions such as SASE solutions.
Monitoring both incoming and outgoing traffic for any signs of suspicious activity, protecting against malware and other cyber threats while helping prevent data exfiltration or loss.
Costs
Many enterprises find themselves grappling with security challenges as they embrace digital transformation, necessitating an innovative solution to secure networks. That is where SASE comes in; offering a cloud-delivered and fully scalable network architecture which safeguards data and applications at the edge of the network, it serves as an ideal alternative to legacy solutions which may prove both costly and difficult to maintain.
SASE offers an impressive variety of network and security features, such as CASB, ZTNA, and WAN optimization. This solution creates a unified security and networking fabric that helps organizations reduce costs and enhance performance, as well as meeting compliance requirements and protecting against advanced threats. Furthermore, its architecture ensures users do not come in contact with risky applications and services.
Though CASB may provide some relief, it cannot address all the security challenges facing organizations. A CASB could actually cost more than SASE depending on your organization’s security needs and deployment scenario; to get maximum value from your CASB investment, select one which provides complete visibility over all applications and services.
A CASB can help protect against data loss by blocking malicious software, malware, and cyber attacks. Furthermore, these tools allow users to monitor privileged account activity, enforce data privacy policies, monitor privileged account activity of privileged accounts, enforce privacy policies for sensitive data sets, and more. In addition, many CASBs feature additional features, like data leak prevention (DLP), that provide additional security and compliance capabilities.
SASE not only provides security and visibility to businesses, but it can also reduce latency by optimizing routing across a global network of data centers. This technology helps prevent costly connectivity issues while safeguarding essential apps and cloud infrastructure.
SASE can also help reduce network complexity and the need for specialized hardware and appliances, helping your IT team maintain and support less products, cutting costs and increasing efficiency. Furthermore, its cloud-native nature and multitenant architecture makes deployment and management of SASE more manageable.
Scalability
As more companies transition their data and applications to the cloud, protecting these assets from cyber threats becomes ever more vital. Specialized solutions like CASB have arisen as solutions that protect these resources against potential risks; additionally they prevent unauthorised access and adhere to an organization’s security policies.
However, CASBs tend to be limited in scope; their primary role is protecting software as a service (SaaS) applications and cannot protect other cloud resources or the public internet. Therefore it is crucial that any chosen CASB solution offers scalability across an enterprise network.
SASE is an emerging technology that provides greater scalability than traditional network and security solutions. Utilizing edge computing principles, information is processed closer to those who require it – providing greater granular security controls, access control for each user, application or device, while simultaneously decreasing latency through its network of points of presence.
SASE can give you greater visibility and control for all of your applications, from cloud apps and SaaS services to other WAN-based ones. By consolidating networking and security functions into one platform, SASE reduces management complexity while freeing IT up for other tasks. Plus, its more cost-effective than VPNs as it cuts down on connections to central networks while eliminating the need for on-premise infrastructure.
SASE stands apart from traditional network security and analytics solutions by being an all-in-one WAN-based solution that offers real-time monitoring of network performance and applications. It can detect security threats like malware intrusion as well as prevent data leakage – helping organizations avoid costs while speeding up business applications; identify misconfigurations to save both time and money by stopping errors before they happen; stop drift configuration settings with intelligent grouping features to provide remediation solutions more quickly; as well as help stop configuration drift with intelligently group related configuration settings that improve remediation capabilities compared to its counterparts.
Integration
CASB and SASE are two network security solutions, but each approach networking and cybersecurity differently. While CASB primarily targets cloud applications, SASE provides fully integrated WAN networking and security that connects remote users and offices to enterprise applications and the internet. Because these two products serve different types of clientele with unique needs, it is imperative that an understanding of each type of client and selecting an ideal solution be established prior to selecting any particular solution.
Your clients must protect both data and applications in a distributed workforce or multi-cloud environment, making a comprehensive network security architecture which incorporates infrastructure and application layer security essential. A CASB/SASE solution can assist in this endeavour by consolidating networking and security functions into one platform for greater cost and complexity reduction.
A cloud access security broker, or CASB solution, is a software or hardware program that sits between users and cloud services to enforce security policies that enforce cloud-based resources. CASB solutions can detect suspicious activity, block threats, detect shadow IT and protect virtualized environments to keep mission-critical data safe. In addition, they monitor both internal and external networks for threats – meaning if employees use unapproved apps the CASB will alert IT departments immediately so they don’t release malware into your organization or introduce other forms of cyber threats into your organization.
Although CASB addresses many of the security challenges arising from working remotely, its inability to integrate with other security and network services limits its value for many companies. Instead, many choose point solutions like SD-WAN, ZTNA or WAN optimization in order to meet their network and security requirements – creating more complexity and increasing costs in doing so.
SASE is an improved security solution that addresses these challenges by offering comprehensive network and security functionality through one holistic platform. Leveraging zero trust architecture principles, SASE ensures continuous authentication and authorization across devices, users, devices and cloud applications and services with low latency connections optimized to reduce latency issues.
SASE helps organizations remain competitive by enabling them to scale their networks and applications to meet user demand, something which is especially crucial in today’s work-from-anywhere world where employees need access cloud applications from any location. SASE takes an edge-centric approach to security which moves protection closer to users instead of forcing it onto perimeter networks, thus reducing latency while improving security against threats.
Security
Attributed to the increasing growth of cloud-based applications and data, enterprises face unprecedented security challenges. Traditional solutions cannot keep pace with this new threat vector while managing multiple point solutions adds both complexity and costs. To address these problems, SASE was developed as an all-in-one network and security solution combining CASB capabilities with WAN security features to deliver visibility, data protection and threat protection for cloud, mobile and on-premises applications.
CASBs (Cloud Application Security Brokers) are programs that act as intermediaries between users and cloud applications to enforce security policies, providing protection from cyberattacks, virtualized environments and mission-critical data that is kept secure. Furthermore, CASBs help prevent compliance breaches while meeting regulatory requirements as well as detect or block risky or unwanted applications that are potentially harmful or unwanted – as well as being tailored specifically to an organization’s requirements.
While CASBs provide many advantages, they should not be seen as an alternative to VPNs. VPNs are meant to provide secure remote access from remote locations but do not adequately address many of the concerns related to cloud applications and can slow data transmission significantly while adding further complexity to networks – using CASBs with SASE platforms is much more reliable solution.
SASE is a network access control security model utilizing Zero Trust concepts to safely connect users to apps and data. Leveraging identity for access control, it requires continuous authentication and authorization for all connections while taking into account factors like user location, time of day, enterprise security standards as well as ongoing evaluations of risk and trust before making its determinations on whether a connection should be granted or denied.
SASE platforms differ from CASBs in that they do not rely on virtual private networks for functionality; rather they operate at the network edge using its global footprint to route traffic efficiently and safely while helping reduce latency and improving performance while offering secure access to cloud-based apps.
Although CASBs can be deployed independently, they’re typically deployed within an SASE solution. SASE offers an all-encompassing security stack including CASB, optimised network routing via software-defined wide area network (SD-WAN), and next-generation firewall (NGFW) security that allow enterprises to gain full visibility into the cloud while cutting costs and increasing productivity.
