We get asked all the time: "What are the best security tools?" The truth is, there's no right answer. The "best" tool stack for a 10-person startup is going to be very different from the "best" tool stack for a 100,000-person global enterprise.
But we can get you close. We recently sat down with the CISO of a Fortune 500 manufacturing company, who agreed to share their complete, anonymized security tool stack with us. This is a company with a mature security program, a multi-billion dollar revenue stream, and a target on its back from both cybercriminals and nation-state actors. This is what they're using to defend themselves.
The Philosophy: This CISO's approach can be summed up in one phrase: "best-of-breed, integrated." They don't believe in the "single pane of glass" from a single vendor. Instead, they've carefully selected what they believe to be the best tool in each category and have invested heavily in the engineering resources to integrate them into a cohesive security fabric.
The Stack:
* Endpoint: They're a CrowdStrike shop. They were an early adopter of EDR and have a deep and long-standing relationship with CrowdStrike. They use the full suite, from Falcon Prevent (NGAV) to Falcon Insight (EDR) to Falcon Complete (MDR). * Cloud: They have a multi-cloud environment (AWS and Azure) and use Wiz as their CSPM. They chose Wiz for its agentless approach and its ability to provide a single, unified view of risk across both clouds. They also use a handful of native cloud security tools, like AWS GuardDuty and Azure Sentinel, but Wiz is their primary source of truth for cloud risk. * Network: They're a Palo Alto Networks shop for their firewalls, but they're increasingly moving to a zero-trust model with Zscaler. They use Zscaler Private Access (ZPA) for secure access to internal applications and Zscaler Internet Access (ZIA) for secure web gateway and cloud firewall capabilities. * Identity: Like most large enterprises, they're an Okta shop. They use Okta for single sign-on (SSO), multi-factor authentication (MFA), and lifecycle management. They've also started to roll out Okta's new identity governance and administration (IGA) product. * Data: They use Varonis for data security and governance. Varonis gives them visibility into who is accessing what data, where, and when. It's a critical tool for them, especially given the amount of sensitive intellectual property they have. * SIEM/SOAR: This was the most interesting part of the conversation. They recently ripped out their legacy SIEM (Splunk) and replaced it with a combination of Snowflake and a new security data lake startup. They're using Snowflake as their "security data lake," ingesting logs from all their other tools. They then have a small team of data scientists and security engineers who are building their own custom detections and analytics on top of Snowflake. For SOAR, they're using Tines, which they chose for its flexibility and ease of use.
What they're cutting: The big surprise was their decision to move away from Splunk. The CISO said the cost had become "untenable" and that they were getting more value from building their own analytics in Snowflake. They're also actively looking to consolidate their vulnerability management tools. They currently use both Tenable and Qualys but are planning to standardize on one in the next year.
The takeaway: This is what a modern, at-scale security program looks like. It's a mix of established leaders and innovative startups. It's built on a foundation of best-of-breed tools, but with a heavy emphasis on integration and custom engineering. And it's a reminder that the security tool landscape is constantly evolving. The "best" tool stack today won't be the "best" tool stack tomorrow.
