Cybersecurity Tech Stack Trends: What Companies Are Deploying

Cybersecurity Tech Stack Trends: What Companies Are Deploying

The cybersecurity technology landscape has undergone a fundamental transformation over the past several years. The perimeter-based security model that dominated enterprise IT for decades has given way to a layered, identity-centric approach driven by cloud migration, remote work normalization, and an increasingly sophisticated threat landscape. For security vendors, MSSPs, channel partners, and market researchers, understanding what companies are actually deploying, not just what analysts recommend, is essential for strategic planning, competitive positioning, and sales targeting.

This analysis examines cybersecurity technology adoption across company sizes, covering web application firewalls, SIEM platforms, endpoint protection, zero-trust architectures, and emerging categories. We draw on technographic data from company technology profiles to show what organizations are running in production, not what they aspire to run, and what these trends mean for vendors selling into the security market.

The State of Cybersecurity Technology Adoption

Security Spending Context

Global cybersecurity spending is projected to exceed $215 billion in 2026, continuing a multi-year growth trajectory driven by regulatory requirements, board-level awareness of cyber risk, and the expanding attack surface created by cloud-native architectures and AI-powered applications. But spending is not distributed evenly. Enterprise organizations with dedicated security teams account for the majority of spending, while small and mid-market companies often rely on built-in security features from their cloud and infrastructure providers.

This spending disparity creates distinct technology adoption patterns across company sizes, and understanding these patterns is critical for vendors deciding where to focus their go-to-market efforts.

How Company Size Drives Security Stack Decisions

The cybersecurity tools a company deploys correlate more strongly with company size and engineering maturity than with industry or geography. A 50-person SaaS startup and a 50-person law firm may be in completely different industries, but their security technology decisions are shaped by similar constraints: limited budget, no dedicated security team, and a preference for tools that work out of the box.

Understanding these size-based adoption patterns helps security vendors prioritize their target accounts. You can search companies by technology on StackWho to see which organizations are using specific security tools and identify prospects that match your ideal customer profile.

Web Application Firewall (WAF) Adoption

Market Landscape

Web application firewalls have become table stakes for any company with a web-facing application. The market has consolidated around cloud-native offerings:

• Cloudflare WAF: The most widely deployed WAF across all company sizes. Its bundled approach (WAF + CDN + DDoS protection + DNS) makes it the default for companies wanting security without managing separate tools.
• AWS WAF: Dominant among AWS-native architectures thanks to native integration with ALBs, API Gateway, and CloudFront.
• Akamai: Holds significant enterprise share, particularly in media, e-commerce, and financial services.
• Imperva and Fastly: Imperva is strong in regulated industries; Fastly’s Signal Sciences is growing among DevOps-mature organizations.

Adoption by Company Size

• Startups and SMBs (1-200 employees): Cloudflare dominates this segment with an estimated 55-65% share of WAF deployments. Many small companies use Cloudflare’s free or Pro tier, which includes basic WAF rules, making it the lowest-friction entry point for web application security.
• Mid-market (200-2000 employees): A mix of Cloudflare and cloud-native WAFs (AWS WAF, Azure WAF, Google Cloud Armor). Companies in this segment typically choose whichever WAF integrates most cleanly with their primary cloud provider.
• Enterprise (2000+ employees): More diverse WAF deployments, often running multiple WAFs for different applications. Akamai, Imperva, and F5 maintain stronger positions in this segment alongside cloud-native options.

What This Means for Security Vendors

The WAF market is mature and highly consolidated. For vendors competing in this space, differentiation increasingly comes from adjacent capabilities: bot management, API security, and runtime application self-protection (RASP). Companies evaluating their WAF strategy are often also looking for solutions to these adjacent problems, creating cross-sell opportunities for vendors with broader application security platforms.

Track which companies are using basic WAF tiers versus advanced security platforms by searching for specific security technologies on StackWho. Companies on basic WAF tiers that are growing rapidly represent upgrade opportunities for vendors with more sophisticated offerings.

SIEM and Security Operations

The SIEM Market Transformation

Security Information and Event Management (SIEM) has undergone perhaps the most dramatic transformation of any cybersecurity category. The legacy SIEM model, characterized by on-premise deployments, complex correlation rules, and per-gigabyte pricing that punished data growth, has given way to cloud-native security analytics platforms that emphasize usability, automation, and predictable pricing.

The current SIEM landscape includes:

• Microsoft Sentinel: Rapidly gaining market share, particularly among companies with significant Microsoft 365 and Azure footprints. Sentinel’s native integration with the Microsoft ecosystem and consumption-based pricing make it attractive for organizations already committed to Microsoft infrastructure.
• Splunk (now part of Cisco): Still the most widely deployed SIEM in large enterprises, though its market share in new deployments is declining. Cisco’s acquisition has raised questions about long-term product direction and pricing.
• CrowdStrike Falcon LogScale (formerly Humio): Growing rapidly among organizations that value high-performance log analytics and already use CrowdStrike for endpoint protection. The combination of endpoint telemetry and log analytics on a single platform is a compelling story.
• Google Chronicle (now part of Google Security Operations): Google’s security analytics platform leverages Google’s infrastructure scale to offer predictable pricing regardless of data volume. Adoption is growing among companies running on Google Cloud and those frustrated with volume-based SIEM pricing.
• Elastic Security: The open-source option in the SIEM market, popular with organizations that want to self-host their security analytics or need to integrate SIEM data with existing Elasticsearch deployments.
• Panther, Sumo Logic, and emerging players: A growing number of cloud-native SIEM alternatives target specific segments. Panther focuses on security teams with engineering DNA, while Sumo Logic offers integrated observability and security analytics.

Adoption Patterns

SIEM adoption is strongly correlated with company size due to both cost and operational complexity:

• Startups and small companies: Most do not run a traditional SIEM. They rely on cloud provider logging (CloudTrail, GCP Audit Logs), basic alerting, and manual incident response. Some use lightweight alternatives like Blumira or Panther.
• Mid-market companies: This is the most active segment for new SIEM deployments. Microsoft Sentinel and Google Chronicle are gaining the fastest here, driven by cloud-native deployments and predictable pricing models.
• Enterprise: Splunk remains entrenched but faces growing competition from Sentinel and CrowdStrike. Many enterprises run hybrid SIEM deployments during multi-year migration projects.

Endpoint Protection and EDR

Market Consolidation

The endpoint protection market has consolidated around three major platforms combining next-generation antivirus with endpoint detection and response (EDR):

1. CrowdStrike Falcon: The market leader in cloud-native endpoint protection, particularly strong among technology companies and organizations with sophisticated security teams.
2. Microsoft Defender for Endpoint: Rapidly gaining share by leveraging its inclusion in Microsoft 365 E5 licensing, giving organizations endpoint protection at no incremental cost.
3. SentinelOne: Strong in the mid-market with its autonomous, AI-driven approach. Its Singularity platform combines endpoint, cloud, and identity protection.

Other players include Palo Alto Cortex XDR, Sophos, and Trend Micro, but new deployments are increasingly concentrated among the top three.

The Microsoft Effect

Microsoft Defender deserves special attention because its bundled E5 licensing model is reshaping the competitive landscape. Companies upgrading to Microsoft 365 E5 get endpoint protection included, creating a massive installed base even among organizations that would have chosen a different EDR in a standalone evaluation. For competing vendors, the pitch must shift from “you need endpoint protection” to “you need better endpoint protection than what is already included in your Microsoft license,” which is a harder argument for budget-conscious mid-market companies.

To understand which companies might be receptive to third-party EDR solutions versus satisfied with Microsoft’s offering, search for companies by their technology stack and look for indicators of security maturity that suggest they would invest in best-of-breed tools.

Zero Trust Architecture Adoption

From Buzzword to Implementation

Zero trust has graduated from a theoretical framework to an active implementation priority for most large organizations. The core premise, never trust, always verify, has been operationalized through specific technology categories:

• Identity and access management (IAM): Okta and Microsoft Entra ID (formerly Azure AD) dominate the cloud IAM market. Every zero trust implementation starts with identity as the primary security perimeter.
• Zero trust network access (ZTNA): Zscaler, Palo Alto Prisma Access, and Cloudflare Access lead this category, replacing traditional VPN architectures with identity-aware, per-application access controls.
• Microsegmentation: Illumio, Guardicore (now part of Akamai), and cloud-native network policies provide east-west traffic controls within data centers and cloud environments.
• Secure access service edge (SASE): Zscaler, Netskope, Palo Alto Prisma SASE, and Cato Networks offer converged networking and security platforms that implement zero trust principles across distributed workforces.

Adoption Reality Check

Despite the industry hype, zero trust adoption is uneven:

• Large enterprises: Most have active zero trust initiatives, but implementations are typically partial, with ZTNA for remote access but traditional segmentation in data centers.
• Mid-market: Adoption is accelerating via integrated SASE platforms, often implemented as part of cloud migration rather than as a standalone initiative.
• Small businesses: Minimal explicit adoption, though many are accidentally implementing zero trust principles through cloud-native tools that enforce identity-based access by default.

Implications for Vendors

The zero trust market is still in its growth phase, which means the competitive dynamics are different from mature categories like WAF or endpoint protection. Vendor selection is less entrenched, switching costs are lower, and companies are more willing to evaluate new solutions. For startups and emerging vendors in the ZTNA, SASE, and microsegmentation categories, the window for market entry is still open.

Target companies that have adopted cloud IAM but have not yet deployed ZTNA or SASE solutions. These companies have taken the first step on their zero trust journey (identity) but have not yet committed to a vendor for the networking and access control layers. Search for companies using Okta or Azure AD on StackWho to identify these partially-deployed zero trust prospects.

Cloud Security Posture Management and CNAPP

The Rise of Cloud-Native Security

As companies migrate workloads to cloud infrastructure, a new category of security tools has emerged to address cloud-specific risks. Cloud Security Posture Management (CSPM) and the broader Cloud-Native Application Protection Platform (CNAPP) category have grown rapidly. Wiz has captured significant market share with its agentless approach, while Palo Alto Prisma Cloud and Orca Security compete with comprehensive CNAPP offerings. Many companies start with AWS-native tools like Security Hub and GuardDuty before evaluating third-party platforms.

CSPM and CNAPP adoption is driven almost entirely by cloud infrastructure maturity. Companies running Kubernetes, using multiple cloud providers, or deploying serverless architectures are prime targets. You can identify these companies by searching for cloud infrastructure technologies on StackWho and looking for organizations with complex cloud deployments that likely need specialized security tools.

Emerging Cybersecurity Categories to Watch

AI Security

As companies deploy AI and machine learning models in production, a new category of AI security tools is emerging to address risks specific to AI workloads: model poisoning, prompt injection, training data exfiltration, and AI-generated content abuse. Companies like Protect AI, HiddenLayer, and Robust Intelligence are early leaders in this space.

AI security is still a nascent market, but adoption will accelerate as regulatory frameworks for AI safety mature and as AI-related security incidents drive board-level awareness. Vendors in this space should target companies that have recently adopted AI infrastructure (GPU compute, vector databases, ML platforms) as their primary prospect pool.

Software Supply Chain Security

High-profile supply chain attacks (SolarWinds, Log4j, the xz utils backdoor) have driven investment in software supply chain security. This category spans software composition analysis (Snyk, Sonatype, Mend), SBOM generation platforms, code signing tools like Sigstore, and container image scanning with Trivy and Anchore. Adoption is highest among companies with mature DevSecOps practices and those selling to government customers who must comply with NIST supply chain guidelines.

Identity Threat Detection and Response (ITDR)

As identity becomes the primary security perimeter, attackers have shifted focus to compromising identities rather than networks. ITDR detects and responds to credential stuffing, MFA bypass, token theft, and privilege escalation. CrowdStrike, Microsoft, and startups like Silverfort are building ITDR capabilities, and this category will grow significantly as organizations realize that deploying IAM and MFA alone is not sufficient.

What These Trends Mean for Security Vendors

The Consolidation Imperative

One of the strongest trends in cybersecurity buying behavior is platform consolidation. CISOs managing 60-80 security tools are actively reducing vendor count in favor of platforms that cover multiple categories. Palo Alto Networks, CrowdStrike, Microsoft, and Zscaler are the primary beneficiaries of this trend, each expanding their platforms to cover adjacent security categories.

For point-solution vendors, this creates a challenging dynamic. Even if your product is technically superior in its specific category, buyers may choose a platform vendor’s “good enough” offering because it reduces complexity, integration burden, and vendor management overhead.

The Mid-Market Opportunity

While enterprise budgets are large, the mid-market segment (200-2000 employees) represents the greatest growth opportunity for security vendors. These companies are large enough to have real security requirements but small enough that they have not yet committed to a single platform vendor. They are actively building their security stacks and are receptive to tools that deliver value quickly without requiring a large security team to operate.

Identify mid-market companies with specific technology profiles that indicate security maturity and readiness to invest. StackWho’s company search lets you find companies by the technologies they use, helping you build targeted account lists of mid-market organizations with the infrastructure profile that matches your security product’s ideal customer.

Selling With Technology Context

Cybersecurity sales increasingly require technology-specific positioning. A SIEM vendor pitching to a company running entirely on AWS needs a different message than one pitching to a multi-cloud environment. An endpoint security vendor competing against Microsoft Defender needs to lead with capabilities that Defender lacks rather than generic EDR value propositions.

Technographic data enables this contextual selling. By understanding a prospect’s existing security tools and broader technology infrastructure before making contact, security sales teams can craft outreach that addresses specific gaps, integration opportunities, and pain points rather than leading with generic security messaging that gets lost in the noise.

Looking Ahead

The cybersecurity technology landscape will continue evolving rapidly as attack surfaces expand and threats become more sophisticated. The companies that succeed, both as security vendors and as security buyers, will be those that make data-driven decisions about which technologies to deploy and which to sell into. Technographic intelligence from platforms like StackWho provides the ground-level view of what companies are actually running in production, which is ultimately more valuable than analyst predictions or vendor marketing claims.

For security vendors, the actionable takeaway is clear: understand your prospects’ existing technology stacks before you engage. Know what security tools they already use, what cloud infrastructure they run on, and what technology transitions they are undergoing. This context transforms generic security sales into consultative conversations that resonate with increasingly sophisticated buyers who can tell the difference between a vendor that understands their environment and one that is simply running through a pitch deck.
