Top 12 Cloud Security Tools for 2021

A recent survey of nearly 2,000 IT professionals found that while most (85%) enterprises believe cloud technologies are critical to innovation, only 40% actually have a security policy in place. On top of this, almost half of the respondents using cloud infrastructure reported their engineers and developers circumvent or ignore cloud security and compliance policies, demonstrating the importance of automation and monitoring technology.

As expected, malefactors followed the corporate crowd. In 2020, cloud services saw a 600% rise in attacks on their services. In the last few years, cloud misconfigurations alone cost businesses almost $5 trillion and led to the release of over 33 billion user records. So it is no surprise to know that the cloud security market is expected to grow to a market size of over $68 billion by 2025. 

Why Do DevOps Need Cloud Security Tools?

Most organizations are more concerned with hitting product delivery deadlines than handling development security right from the very start, often relegating security toward the end of the production schedule. The rationale behind this false assumption is that dealing with security may cause production delays. While this assumption may have been correct years ago, new tools and services that smoothly integrate into the CI/CD pipeline have matured to a point where this is no longer the case.

Beyond baseless fears, the cloud infrastructure is a vast wonderland of powerful features and capabilities representing a complex weave of technologies that are impossible to secure without specialized tools and solutions genuinely.

Before we list them, let's review the most essential cloud security tool categories you need to know before you start.

Types of cloud security tools

Cloud security tools break down into six primary categories that fulfill a particular role in protecting cloud databases, applications, and containers:

Table of contents

  1. CASB -- Cloud Access Security Brokers
  2. SAST -- Static Application Security Testing
  3. SASE -- Secure Access Service Edge
  4. CSPM -- Cloud Security Posture Management
  5. CWPP -- Cloud Workflow Protection Platforms
  6. CIEM -- Cloud Infrastructure Entitlement Management

What do all these four-letter acronyms mean? And what type of solutions do you need to keep your cloud data and services secure? Let's break it down.

What are Cloud Access Security Broker (CASB) Tools?

Cloud Access Security Broker (CASB) tools encapsulate your on-campus or cloud-hosted security solutions. CASB can be both physical and digital solutions, which function as a stop-gap and gateway between users and cloud service providers.

This extends to IaaS, PaaS, and some (a limited amount) of SaaS environments. Boiled down, CASB plugs security holes by allowing organizations to extend their security policies beyond just the campus to the cloud and create cloud-only security controls as well. CASB tools are based on four base concepts:

  • Data Protection
  • Threat Protection
  • Identity
  • Visibility

If an organization's highest priority is visibility into SaaS application usage and access, a CASB tool will be the ideal solution. These tools are the most mature and established in cloud security and comparatively broader than other cloud security tool types.

The most popular use cases for SAST are:

  • Scanning for exposed secrets such as passwords, API keys, and security tokens in source code or binaries.
  • Continuously monitor and detect dangerous vulnerabilities in open-source libraries.
  • Creating a digital inventory of third-party assets used in the development environment or on a production website.
  • Analyzing third-party asset behavior, where data is sent, and possible security threats.
  • Assuring Compliance with Open-Source license terms.

What are Cloud Security Posture Management (CSPM) Tools?

CSPM tools are a good choice for organizations oriented around Infrastructure, Software, and Platform as a Service (IaaS, PaaS) and looking to automate security management. Unlike SSPM solutions, CSPM tools focus on controlling access to cloud infrastructure tools deployed and employed by an organization. These tools are relevant for organizations in the process of migrating their operations to a cloud service. 

CSPM tools excel at helping organizations become and remain security standard compliant, with easy configuration and deployment. CSPM tools operate by consistently seeking out misconfigurations and making any necessary changes automatically. These solutions are ideal for enterprises focused on detecting, assessing, logging and reporting, and automating issue remediation.

What are Cloud Workload Protection Platforms (CWPP)?

CWPP security tools are enterprise workload-focused cloud platforms that offer protection to both physical and digital assets, including containers, virtual machines, and serverless workloads. 

Due to organizations' frequent reliance on legacy apps and frameworks, a complete move to the cloud is usually more trouble than it is worth. CWPP solutions bridge the security gap between legacy components and those on the cloud. They offer discovery and management of already-deployed workloads on your public and on-campus cloud ecosystems. 

CWPP solutions are great for any organization that is not centralized in one location but is spread out geographically or digitally by design and needs to maintain universal security standards. They differ from other cloud security solution types in that they rely on gathering information from operating systems instead of APIs.

What are Cloud Infrastructure Entitlement Management (CIEM) tools?

CIEM is a cloud security solution that excels at managing the complicated security situation that Identity and Access Management (IAM) creates. 

CIEM tools are focused on the identity lifecycle and access governance controls, which are intended to reduce unnecessary entitlements and enforce least-privilege access for users across the cloud network. This also limits the need for intervention necessary to detect and remove over-privileged user access, which can be exceedingly time-invested.

These tools provide deep visibility into data access vulnerabilities and entitlement risks. Unlike other solution categories, which often offer a more broad, holistic view of an organization's cloud network. Organizations struggling with data access complications and looking for complete management and control over multiple policy types would benefit most from CIEMs.

Beyond the cloudy sky

Cloud network reliance and usage are spiking to record levels as day-to-day business activity becomes increasingly dependent on a growing number of IaaS, PaaS, and SaaS cloud services.

This has thrust cloud security into the spotlight, along with the necessity for enterprises and public organizations to protect their cloud activities.

The slightest mishap in configuring your cloud infrastructure and reliance on cloud platforms' built-in security to protect your cloud assets can lead to significant breaches. SAST is not a sassy acronym. It's a vital security model that plugs organizational leaks. Tasty secrets such as Passwords, API keys, security tokens, and other secrets are just waiting to be exploited by malicious actors. And not unlike a leaky ship, leaking information can sink your organization.

This is why it is vital to invest in cloud security tools to proactively find and eliminate vulnerabilities in your infrastructure, both physical and virtual.
