Atmosec

# Atmosec: High-Level Overview

Atmosec is a SaaS security platform company that addresses a critical gap in enterprise cloud infrastructure—the security of interconnected SaaS applications[1]. Founded in January 2021 and based in Tel Aviv, Israel, Atmosec built an automated security solution designed to monitor, assess, and protect hyperconnected SaaS ecosystems as they evolve[1][2].

The company solves a specific but increasingly urgent problem: as organizations adopt multiple SaaS applications that communicate with each other, they lose visibility into these connections and become vulnerable to malicious SaaS-to-SaaS communications, misconfigurations, and unauthorized data flows[2]. Atmosec's platform uses machine learning to identify anomalies, automatically discover malicious applications, and enforce security controls—all without requiring manual intervention at scale[1][2]. The company demonstrated strong early traction, raising $6M in funding before being acquired by Check Point Software Technologies in September 2023[1][2].

# Origin Story

Atmosec emerged in 2021 at a pivotal moment when SaaS adoption was accelerating but security practices had not kept pace[1]. The founding team, based in Tel Aviv's thriving cybersecurity ecosystem, identified that traditional security tools were blind to the risks posed by third-party SaaS applications interacting within enterprise environments[2]. By the time of its acquisition announcement in September 2023, the company had grown to 17 employees and had already gained recognition as an innovative early-stage startup[2]. The rapid path to acquisition—less than three years from founding—reflected both the urgency of the market problem and the quality of the solution.

# Core Differentiators

Atmosec's platform stood out through several key capabilities:

• Speed of discovery and response: The platform could identify and disconnect malicious SaaS applications in under 10 minutes, a critical advantage in preventing data breaches[2]
• Full ecosystem visibility: Unlike point solutions, Atmosec monitored an unlimited number of third-party SaaS services and their interactions with each other, providing comprehensive visibility into both authorized and unauthorized applications[1][2]
• Automated risk mitigation: The platform proactively flagged anomalies and misconfigurations—such as publicly exposed repositories—and could enforce controls like multi-factor authentication without manual intervention[2]
• Machine learning-driven detection: Rather than relying on static rules, Atmosec used ML to identify behavioral anomalies and emerging threats in real time[1]

# Role in the Broader Tech Landscape

Atmosec rode the wave of SASE (Secure Access Service Edge) consolidation, a market trend where security vendors integrated multiple capabilities—internet access, zero-trust private access, SaaS security, and SD-WAN—into unified platforms[1]. The timing was critical: as remote work normalized and cloud-native architectures became standard, the attack surface expanded dramatically, and SaaS security became a board-level concern rather than a technical afterthought.

Check Point's acquisition of Atmosec, announced alongside the acquisition of Perimeter 81, reflected a strategic shift in the cybersecurity industry toward comprehensive cloud security[1]. By integrating Atmosec into Check Point Infinity, the acquirer positioned itself to address the specific blind spots that traditional network-centric security tools could not see—the lateral movement and data exfiltration risks within SaaS ecosystems themselves.

# Quick Take & Future Outlook

Atmosec's acquisition by Check Point validates that SaaS security is no longer a niche concern but a core pillar of enterprise security architecture. The company's technology is now embedded within Check Point Infinity, where it will be incrementally released to the broader customer base[2]. Rather than remaining an independent startup, Atmosec's impact will be amplified through Check Point's established enterprise relationships and distribution channels.

The broader implication: as organizations continue to adopt more SaaS applications and build increasingly complex integrations between them, the visibility and automation capabilities that Atmosec pioneered will become table stakes for any serious enterprise security platform. The company's journey from founding to acquisition in under three years underscores how quickly market urgency can translate into strategic value in cybersecurity.
