The 5 Most Popular Cloud Security Vendors in 2025

Cloud security is more important than ever. As brands increasingly use cloud-based software platforms and security, they need to ensure that their customer's private data is kept safe and sound 24/7.
Fortunately, there are lots of popular cloud security vendors to choose from, especially in 2025. Let’s take a closer look so you know who to call to shore up your company’s digital defenses.
1. Astra Security
One of the most popular cloud security providers in the industry, Astra Security offers a lot to like—starting with its automatic vulnerability scanner. The scanner can conduct over 8,000 tests to detect vulnerabilities, matching potential problems against extensive vulnerability databases. They also have an AI-assisted engine that offers business logic test cases, false positive triaging, and a personal security assistant bot.
That’s not all Astra Security offers. It can also perform compliance checks against industry standards such as the ISO27001, HIPAA, and SOC 2 to ensure easy compliance with cloud-based security regulations.
Then there’s the Astra Pentest dashboard, a cloud tool that is highly CXO-friendly and enables collaboration between real penetration testers and your team members. Astra Security offers a comprehensive cloud security solution and is one of the best vendors to check out.
2. Cipher
Cipher is a cloud security service with many offerings, starting with monitoring services. It automatically collects and enriches data from connected cloud customer networks, enabling you to watch for penetrations and other security threats from users who are connected to your cloud network via applications or mobile devices. They also offer Cipher xMDR, a holistic solution that uses an AI-driven approach to protect businesses from cyber threats.
Cipher also normalizes and analyzes security log data from throughout your network, providing comprehensive monitoring 24/7. Other services include ensuring regulatory compliance, improving your overall cyber defenses, and helping you create a resilient security architecture.
3. Datadog
Datadog, also called Datadog Security Monitoring, is a cloud security vendor that offers real-time threat analysis across your cloud network, including all your connected applications, IT infrastructure, and end terminals or devices.
Datadog supports over 800 built-in integrations, such as GSuite, AWS Cloud, Adobe, Active Directory, and Okta. No matter what your organization happens to be integrated with, Datadog will provide you with accurate and actionable alerts for anomalous and malicious activity patterns, such as possible malware intrusions or penetration tests.
Datadog’s special Detection Rule is a powerful, comprehensive way to let your team detect potential security threats and suspicious behavior using conditional logic. It can detect threats within minutes, as it’s ready and capable of analyzing some of the most popular attacker techniques. Consider using Datadog if your team has some security experience — and wants to customize threat detection rules using Datadog’s built-in editor.
4. Palo Alto Networks
Palo Alto Networks is an all-around cloud malware detection service. It also offers other high-end security capabilities, such as deploying and maintaining a next-generation firewall. Thanks to its streamlined organization and operations, Palo Alto Networks offers threat protection and network speed production for cloud-based businesses. It really offers a massive suite of features, including intrusion detection, data security, firewalls, and web and phishing security.
With zero-day monitoring and an easy setup from day one, Palo Alto Networks could be a great choice for well-established brands in the cloud who need help tackling bigger cloud security challenges. However, note that Palo Alto Networks is a little more expensive than other cloud security vendors. So, keep this in mind when choosing between this provider and another.
