Overview

The Center for Internet Security (CIS) is a forward-thinking, non-profit entity that harnesses the power of a global IT community to safeguard private and public organizations against cyber threats. CIS is best known for developing the CIS Critical Security Controls and CIS Benchmarks, which are internationally recognized as the industry standard for defensive best practices.

Headquartered in East Greenbush, New York, CIS has a storied history rooted in public service and collective defense. The organization grew out of a need for a centralized, neutral body that could provide clear, prioritized guidance in an increasingly complex threat landscape. Today, CIS serves a diverse global audience, ranging from small local businesses and non-profits to Fortune 500 enterprises and government agencies.

CIS operates through several key divisions:

  • CIS Controls & Benchmarks: The core of the organization, providing the framework and configuration guidelines used by millions.
  • Multi-State Information Sharing and Analysis Center (MS-ISAC): Designated by the U.S. Department of Homeland Security as the key resource for cyber threat prevention, protection, response, and recovery for state, local, tribal, and territorial (SLTT) governments.
  • Elections Infrastructure ISAC (EI-ISAC): A specialized division focused on the integrity and security of election systems.
  • CIS Services: Including the CIS SecureSuite membership, which provides specialized tools (like CIS-CAT Pro) and resources for organizations to implement and manage their security posture effectively.

Through these initiatives, CIS bridges the gap between high-level security policy and technical implementation, providing the "how-to" for securing IT infrastructure.

Positioning

CIS positions itself as the "essential foundation" of any cybersecurity program. Their messaging focuses on the concept of "Cyber Hygiene"—the idea that most breaches can be prevented by implementing a core set of well-established best practices. While many competitors position themselves as high-tech shields against advanced persistent threats, CIS positions itself as the foundational logic and structural integrity upon which all other security layers should be built.

Their competitive strategy is built on three pillars:

  1. Authority through Consensus: CIS differentiates itself by being the neutral meeting ground for the world's security experts. They don't just sell security; they define what "secure" looks like.
  2. Practicality and Prioritization: In a market saturated with "all-encompassing" frameworks, CIS positions its Controls as a prioritized list. Their messaging emphasizes "doing the most important things first," which resonates with resource-constrained IT teams.
  3. Ecosystem Integration: CIS doesn't seek to replace other security tools; instead, it positions its Benchmarks and Controls as the standard that other tools should measure against. This allows them to partner with major cloud providers and software vendors who integrate CIS standards directly into their platforms.

By maintaining a non-profit status and focusing on community-vetted standards, CIS occupies a unique space as a trusted advisor and industry arbiter, rather than a traditional software vendor.

Differentiation

The primary product differentiation for CIS lies in the authoritative nature and global recognition of the CIS Critical Security Controls (CIS Controls) and CIS Benchmarks. These are not merely suggestions but are considered the "gold standard" for prescriptive, prioritized, and actionable security guidance. While many security products focus on threat detection, CIS products focus on hygiene and hardening—the foundational elements of security.

Key technical advantages include:

  • CIS Hardened Images: These are pre-configured virtual machine images hardened according to CIS Benchmarks, available across major cloud platforms (AWS, Azure, GCP). They allow organizations to deploy secure instances immediately without manual configuration.
  • CIS-CAT Pro: A specialized configuration assessment tool that automates the process of comparing a system's settings against CIS Benchmarks, providing instant compliance reporting and remediation steps.
  • Prioritization via Implementation Groups (IGs): Unlike many frameworks that overwhelm users with hundreds of requirements, CIS categorizes its controls into IGs based on an organization's size and risk profile, making security attainable for small businesses and enterprises alike.

The innovation at CIS is driven by its consensus-based development. By the time a benchmark or control is released, it has been vetted by a global community of practitioners, ensuring that the recommendations are technically sound, practical for real-world environments, and effective against current threat vectors.

Ideal Customer Profile

The ideal CIS customer is an organization that prioritizes proven, actionable security frameworks over ad-hoc security measures. This spans from mid-market enterprises ($50M+ revenue) to Global 2000 companies and public sector entities. Key characteristics include:

  • Regulated Industries: Finance, Healthcare, Energy, and Government.
