The way businesses operate has fundamentally shifted. According to Gartner, **over 95% of new digital workloads will be deployed on cloud-native platforms by 2025**. At the same time, **cybercrime costs are projected to hit $10.5 trillion annually by 2025 (Cybersecurity Ventures)**. Add to that a hybrid workforce accessing company resources from coffee shops, airports, and living rooms, and suddenly, the corporate perimeter as we once knew it is gone.

This new environment demands security like **Secure Web Gateways (SWG)** and **Cloud Access Security Brokers (CASB)**. While they're often mentioned together, each plays a unique role in protecting your people, data, and reputation. 

In this blog, we'll break down the **CASB vs SWG** comparison, real-world applications, and how to choose the right fit for your business.

## What is a Secure Web Gateway (SWG)? {#what-is-swg}

A Secure Web Gateway is a security solution that filters and monitors internet traffic to prevent malicious threats, enforce company policies, and protect sensitive information. Think of it as a checkpoint between your users and the internet. 

Whether staff are working in HQ or remotely, an SWG filters and inspects web traffic in real time, blocking anything suspicious before it reaches your network.

![secure web gateway vs casb- What is a Secure Web Gateway (SWG)?](/blog/assets/2025/what-is-swg.webp)


### Core SWG capabilities:
- **Web filtering** – Stops access to malicious or policy-violating sites
- **Malware detection** – Inspects downloads and traffic for hidden threats
- **Policy enforcement** – Aligns employee browsing with corporate rules

### Business example:

If a finance team member accidentally clicks on a phishing link in a personal email during their lunch break, the SWG intercepts the request and stops the threat in its tracks—potentially saving millions in breach costs.

### Popular doubts:

**1. Is SWG the same as a firewall?**

No, SWG focuses on web traffic filtering, not network perimeter defense.

**2. Is SWG part of SASE?**

  Yes, SWG is a core component in most Secure Access Service Edge frameworks.

**3. Can SWG work for remote employees?**

  Yes, cloud-based SWGs protect users anywhere.

## What is a Cloud Access Security Broker (CASB)? {#what-is-casb}

A Cloud Access Security Broker acts as a security layer between users and the cloud services and SaaS apps they access. CASB provides visibility and control over data stored and shared in cloud applications like Google Workspace, Microsoft 365, Salesforce, and Dropbox.

![secure web gateway vs casb - What is a Cloud Access Security Broker (CASB)?](/blog/assets/2025/what-is-casb.webp)

### Key capabilities of a CASB include:

- **Data security** – Encrypting or tokenizing sensitive information stored in the cloud
- **Cloud app discovery** – Identifying all SaaS tools being used, including shadow IT
- **Data Loss Prevention (DLP)** – Prevents sensitive files from leaking via web channels
- **Threat protection** – Detecting unusual logins, account hijacking, and risky user behavior
- **Compliance support** – Meeting regulations like GDPR, HIPAA, or SAMA

### Business example:

If a sales rep uploads a customer contract to their personal Dropbox, the CASB detects it instantly and either blocks the action or encrypts the file—reducing the risk of a costly data leak.

> **Pro Insight:** With **80% of enterprise workloads now in the cloud** (IDC), CASB is becoming essential for any organization that handles regulated or sensitive data.

### Popular doubts:

**1. Does CASB replace DLP?** 

  No, it often integrates with DLP tools for better coverage.

**2. Is CASB cloud-only?** 

  Primarily, but some solutions extend to on-prem and hybrid apps.

**3. Can CASB stop shadow IT?** 

  Yes, it detects and blocks unauthorized SaaS use.

Secure Web Gateway vs CASB: What Is the Difference?

Cloud apps make work easier, but they also open the door to new security risks. This blog unpacks everything you need to know, like: what is CASB in cyber security, how it works, and why it matters. We break down the core pillars of CASB, share real-world use cases, and help you understand the benefits it brings to your business. 

What is Cloud Access Security Broker (CASB)?


## Introduction {#introduction}

Imagine waking up to find out that your employee leaked your customer data through a cloud app, and now your business is facing lawsuits and a PR disaster. Cloud adoption is evolving rapidly, but many businesses still lack adequate visibility into what cloud apps employees are using, how data is handled, and where its data flows. 

In fact, [Gartner](https://www.gartner.com/en/newsroom/press-releases/2023-11-29-gartner-says-cloud-will-become-a-business-necessity-by-2028) **projects that by 2028**, more than **50% of enterprises** will be using industry-specific cloud platforms to accelerate business strategies, turning cloud from a competitive edge into a business necessity. With tools like **Google Workspace, Microsoft 365, Salesforce, Zoom,** and others becoming foundational to daily operations, securing cloud access is no longer optional; it’s urgent.

## What is Cloud Access Security Broker (CASB)? {#what-is-casb}

A **Cloud Access Security Broker (CASB)** is a security solution that monitors, controls, and secures all the interactions your users have with work applications, either on-premise or cloud-delivered. 

**CASB defined** in simplest terms: it’s a security tool that applies enterprise-grade policies across all cloud environments, like SaaS platforms. That includes **file-sharing, messaging, collaboration tools, cloud storage, CRM software, and more**.

*“Gartner predicts that by 2025, **80% of enterprises** will have implemented a unified access strategy for web, cloud services, and private applications through a **SASE or SSE architecture**, a sharp rise from just **20% in 2021**.”*

## How Does CASB Work? A Step-by-Step Breakdown {#how-does-casb-work}

If you’re wondering **how a CASB works**, here’s a simple breakdown:

### Step 1: Monitor and Analyze User Activity

Learn what Cloud Security Posture Management is and how it can help you:

- Gain visibility into your cloud environment
- Identify and fix security misconfigurations
- Proactively address security threats
- Ensure compliance with regulations

&nbsp;

Read this blog to take control of your cloud security posture!

## What is Cloud Security Posture Management (CSPM)?

Did you know that approximately [125 million user records were exposed](https://www.scmagazine.com/news/google-firebase-may-have-exposed-125m-records-from-misconfigurations) by over 900 improperly configured websites in March 2024? This incident is just one of many that show how difficult it is for companies to secure their cloud environments. 

&nbsp;

Fortunately, there's a solution: Cloud Security Posture Management (CSPM). It is a security practice that helps businesses fix any security weak spots in their cloud setup and keeps their cloud apps and data safe.

&nbsp;

CSPM cloud security prevents misconfigurations, detects & mitigates threats, and solves non-compliance issues across various cloud platforms, including PaaS, IaaS, and SaaS. By integrating with a [CASB solution](https://www.miniorange.com/casb/), CSPM can look out for the entire cloud setup, check for risks, spot any unauthorized access, and do a lot more to make using the cloud smooth and safe.

&nbsp;

Keep reading to discover how CSPM can help protect your cloud environment.

## Why is CSPM important? {#cspm-important}

As businesses start using the cloud more, they must make sure their security policies are in check. Cloud Security Posture Management is super important for cloud admins who are always on the lookout for security risks. Traditional security practices that involve manual processes are inadequate in this context. They fail to keep pace with the rapid deployment cycles and dynamic changes within cloud environments. 

Following are the reasons why organizations should use CSPM cloud security:

&nbsp;

**Lack of visibility:** Businesses struggle to keep track of their cloud technologies, leading to security risks, compliance issues, and wasted IT budgets. Poor visibility means potential problems and misconfigurations may go unnoticed. This can amplify other IT challenges and slow down digital growth. CSPM gives businesses clear visibility so they can efficiently scale and manage their cloud infrastructure.

&nbsp;

**Compliance challenges:** Manual compliance processes cannot keep up with rapidly scaling cloud architectures. Companies need to always check that they're following important guidelines and regulatory frameworks, including NIST CFS/SP/800-171/800-53, PCI DSS, SOC2, HiTrust, and CIS benchmarks for cloud vendors such as Azure, AWS, GCP, and Alibaba, to avoid big fines. CSPM helps companies automatically ensure they're keeping up with these rules and their own special ones.

&nbsp;

**Lack of context:** Companies need better tools to understand and prioritize these mistakes. CSPM cloud security provides them with context around identified misconfigurations to prioritize or focus on the misconfigurations that pose a risk to their environment. It can help organizations reduce alert fatigue and only address legitimate cloud concerns. 

&nbsp;

**Operational effectiveness:** Companies are using modern methods like DevOps to enhance cloud services, but old security tools often can't keep up. Security checks are slow compared to the speedy development processes. Cloud Security Posture Management solves this by integrating security early in the software creation process, known as 'shift left'. This allows developers to understand and fix security issues quickly. The result is fast and safe software development.

&nbsp;

**Challenges of complex multi-cloud architectures:** Cloud infrastructure lets businesses grow their online services easily but it can complicate things. Adding new apps and resources quickly makes the cloud setup complex. CSPM cloud security helps find and fix security issues in these expanding cloud systems. Managing this growth manually is hard and risky. CSPM makes using cloud services safer and more efficient for companies.

&nbsp;

CSPM helps solve these problems. It keeps an eye on cloud security all the time and makes sure that security can keep up with all the new stuff happening in the cloud. It helps prevent policy misconfigurations to prevent unauthorized access to the cloud and set up new security policies to prevent data breaches in their environment.

## How does CSPM work? {#cspm-work}

Following CSPM practices ensures cloud data protection. Let's break down how it works into simple steps:

&nbsp;

**Finding Assets:** Cloud Security Posture Management (CSPM) first looks around your cloud and notes down everything it finds. This could be like computers in the cloud (virtual machines), places where data is stored (storage buckets, databases), and apps running in isolated spaces (containers).

&nbsp;

**Checking Configurations:** Once assets are identified, CSPM cloud security compares the configurations to what’s considered safe and the rules that should be followed. It checks for any misconfigurations, such as open ports, weak access controls, or unencrypted data, which could pose security risks.

&nbsp;

**Threat Detection:** Cloud Security Posture Management keeps an eye out for any suspicious activity and potential security threats. It employs anomaly detection techniques to identify unusual behaviors, such as unauthorized access attempts, unusual data transfers, or configuration changes indicative of a security breach.

&nbsp;

**Policy Enforcement:** CSPM cloud security makes sure all security policies and compliance requirements are enforced across the cloud infrastructure. This includes encryption protocols, resource permissions, and access controls, to mitigate security risks effectively.

&nbsp;

**Automated Remediation:** In case of security incidents or policy violations, CSPM cloud security can fix such issues promptly. This could include applying security patches, revoking access from someone, rolling back changes to keep safe, reducing the response time, and minimizing the damage of security incidents.

&nbsp;

**Continuous Monitoring and Reporting:** Cloud Security Posture Management keeps an eye on cloud safety all the time. It generates alerts for security incidents, compliance violations, or deviations from security policies, enabling security teams to take immediate action.

## Benefits of CSPM

Following Cloud Security Posture Management (CSPM) practices bring a lot of benefits for businesses moving to the cloud, such as:

&nbsp;

**Centralized Security:** It makes it easier for businesses to spot security risks early and fix them through a simple, one-stop dashboard. CSPM keeps a close eye on cloud services, who gets in, and what they do, all in real time. This means any security issues can be caught and dealt with quickly, keeping everything running smoothly and securely. 

&nbsp;

**Compliance Ready:** Businesses can use CSPM cloud security to easily meet important rules and safety standards like HIPAA, GDPR, ITAR, PCI DSS, and ISO 27001. It lets companies apply safety rules, keep an eye on how well they're doing with these rules, and create detailed reports to make sure they're following all the necessary policies.

&nbsp;

**Reduced Risk of Data Breaches:** By identifying and addressing cloud vulnerabilities, misconfigurations, and keeping out unwanted visitors in the infrastructure, CSPM cloud security reduces the risk of data breaches and cyber-attacks. It helps protect important information and creative ideas stored online, keeping your business reputation safe and preventing expensive security problems.

&nbsp;

**Deep Visibility:** CSPM cloud security gives you a clear look at how safe your cloud space is. It helps security teams get a full picture of what’s happening in the cloud, from resources being used to who’s accessing them. Businesses can keep a tight grip on their cloud setup, making sure security rules are followed and quickly dealing with any security problems.

&nbsp;

**Cost Effective:** Make the best use of cloud services while keeping costs low related to security. CSPM blocks security problems before they happen, making sure that cloud services are used in the smartest way possible. This way, CSPM helps businesses save money by avoiding the costs of security breaches, breaking rules, and not using resources efficiently.

&nbsp;

**Streamlined Security Operations:** Cloud Security Posture Management makes security easier by automating checking, fixing, and monitoring security issues. This means less hands-on work and smoother security tasks.
