Gartner’s 4Q25 Information Security forecast shows 15 categories capturing half of all new security spending through 2029
Fifteen cybersecurity categories are growing up to three times faster than the overall market, capturing $48.7 billion in new spending by 2029.
That’s nearly half of the $98.4 billion the entire security market will add over the next four years. Cloud Security Posture Management leads the pack at 29.36% CAGR. Cloud Access Security Brokers follow at 24.81%.
Enterprises are fundamentally restructuring their security budgets, and the driver is brutal in its simplicity. Organizations now manage an average of 112 SaaS applications across multiple cloud providers. 82% of misconfigurations are caused by human error, according to Exabeam’s analysis. And Gartner estimates 99% of cloud security failures through 2025 will be the customer’s fault, primarily from these misconfigurations. Manual oversight breaks under this kind of scale. Enterprises are responding by investing in automation that manages what people can’t across hundreds of cloud accounts, thousands of APIs, and millions of attack vectors.
Gartner’s 4Q25 update delivers the clearest signal yet about where enterprise security budgets are heading. The overall information security market grows from $213.5 billion in 2025 to $311.9 billion by 2029 at 10.03% CAGR. These fifteen high-growth categories are expanding at 10.30% to 29.36% CAGR, capturing investment dollars at rates that dwarf legacy security spending patterns.
What makes these categories different
Every high-growth category eliminates manual bottlenecks that break under cloud-native workloads. CSPM scans configurations continuously. CASB provides visibility into unauthorized SaaS usage. ZTNA verifies every connection rather than trusting the network location. With 79% of organizations using multiple cloud providers, according to Spacelift’s research, manual processes create mathematical impossibilities.
These technologies prevent problems rather than clean up after them. CSPM catches misconfigurations before breaches. ZTNA eliminates the attack surface that VPNs create. Tokenization protects data even when systems get compromised. Security teams are finally getting ahead of threats instead of constantly playing catch-up.
And the ROI is quantifiable. IBM’s 2025 Cost of a Data Breach Report shows organizations using AI and automation extensively save $1.9 million per breach and reduce breach lifecycles by 80 days. U.S. breach costs average $10.22 million. These investments pay for themselves with a single prevented incident—a calculation CFOs understand.
The 15 categories reshaping enterprise security
1. Cloud Security Posture Management (CSPM) — 29.36% CAGR — $4.68B → $12.76B
CSPM platforms scan infrastructure continuously across AWS, Azure, and Google Cloud, automatically remediating misconfigurations before they become breaches. The 82% human error rate isn’t going to improve through training. Organizations managing 100+ cloud accounts need automation. CSPM adds $8.09 billion in new spending by 2029, the single largest dollar contribution among high-growth segments.
2. Cloud Access Security Brokers (CASB) — 24.81% CAGR — $2.30B → $5.58B
Here’s the brutal reality. Enterprises average 112 SaaS applications, but shadow IT accounts for 42% of all applications per JumpCloud’s data. IT stays blind to roughly 78 apps out of an average 187-app environment. The damage? 65% of shadow IT deployments result in data loss, and 52% lead to breaches, according to Mimecast research. CASBs restore visibility and control, growing to $5.58 billion by 2029.
3. Zero Trust Network Access (ZTNA) — 21.95% CAGR — $2.48B → $5.43B
ZTNA replaces the VPN model with application-specific access controls. Instead of network-level access, it provides application-specific connections verified for every request. Gartner predicts 70% of new remote access deployments will use ZTNA by 2025, up from less than 10% at the end of 2021. And 65% of companies plan to retire VPNs within one year per Cybersecurity Insiders data. This represents a wholesale rethinking of secure access. The perimeter-based model is dying. Good riddance.
4. Threat Intelligence — 21.73% CAGR — $2.58B → $5.69B
Modern threat intelligence platforms fuse telemetry from open-source intelligence, dark-web monitoring, vendor feeds, and internal logs. Machine learning prioritizes indicators based on organizational relevance. IBM data shows organizations integrating threat intelligence reduce detection and escalation costs while cutting incidents by 30%. The market reaches $5.69 billion by 2029 as enterprises shift from passive threat feeds to automated response integration.
5. Cloud Workload Protection Platforms (CWPP) — 21.53% CAGR — $5.98B → $13.11B
Traditional endpoint security can’t protect containers that spin up and vanish in seconds. Serverless functions executing for milliseconds? Legacy tools weren’t designed for that. CWPP solutions instrument workloads directly at the kernel or hypervisor level, monitoring system calls, file access, and network connections in real-time. The 21.53% CAGR reflects the rapid shift toward microservices and Kubernetes. As workloads migrate into container clusters, protecting them becomes a survival-level priority.
6. Consent and Preference Management — 20.22% CAGR — $0.81B → $1.64B
GDPR fines surpassed €5.88 billion by January 2025, according to DLA Piper’s annual survey. California’s CCPA penalties keep climbing. The California Privacy Protection Agency recently fined Todd Snyder $345,178 for inadequate opt-out and privacy request processes. Manual consent workflows can’t meet regulatory deadlines across jurisdictions. Automated platforms centralize preferences across web, mobile, and API endpoints while providing auditable logs for regulators.
7. Subject Rights Request (SRR) Automation — 14.26% CAGR — $1.24B → $2.01B
When users demand “delete my data,” these platforms automate orchestration across internal systems and third-party vendors. Privacy laws grant individuals rights to access, correct, and delete personal data with strict compliance timelines. SRR automation prevents the penalties that result from manual processing failures at scale, especially as more jurisdictions implement data privacy regulations.
8. Network Detection and Response (NDR) — 13.44% CAGR — $2.15B → $3.37B
NDR platforms establish behavioral baselines using statistical analysis and machine learning. When anomalies appear (unusual lateral movement, data exfiltration attempts, command-and-control traffic), they raise alerts or automatically isolate systems. The mindset shift matters here. Rather than hoping to prevent all attacks, sophisticated organizations invest in rapid detection that minimizes damage when attackers inevitably breach perimeters. Prevention alone isn’t sufficient anymore.
9. Vulnerability Assessment — 13.02% CAGR — $3.48B → $5.60B
Quarterly vulnerability scans are obsolete in CI/CD pipelines deploying multiple times daily. Modern assessment platforms provide continuous scanning integrated with exploit intelligence to prioritize patches based on real-world risk. DevOps teams need vulnerability detection that keeps pace with their deployment cadence. Anything less creates unacceptable exposure windows.
10. Tokenization — 12.68% CAGR — $1.34B → $2.11B
Tokenization replaces sensitive data with non-reversible tokens that can’t be mathematically decoded. The urgency comes from quantum computing advances. NIST finalized post-quantum encryption standards in August 2024, including ML-KEM (formerly CRYSTALS-Kyber) and ML-DSA (formerly CRYSTALS-Dilithium). Attackers already practice “harvest now, decrypt later”—collecting encrypted data today for quantum decryption within five to ten years. Organizations must begin quantum-safe transitions now.
11. Endpoint Protection Platform (EPP) — 12.51% CAGR — $17.68B → $28.36B
The largest single category adds $10.68 billion in new spending as ransomware attacks surge. U.S. ransomware attacks increased 149% year-over-year—from 152 incidents in early 2024 to 378 in the same period of 2025, according to Cyble analysis. Next-generation EPP platforms use behavioral analytics and signatureless detection to stop ransomware before encryption begins, catching what traditional antivirus misses.
12. Secure Web Gateway (SWG) — 11.63% CAGR — $4.44B → $6.74B
Malicious sites appear and disappear in hours. Cloud-delivered SWGs update threat intelligence in real-time, protecting remote and hybrid workforces wherever they connect. Integration with ZTNA creates comprehensive security that follows users across devices and locations without relying on network perimeters that no longer exist.
13. Web Application Firewalls (WAF) — 10.92% CAGR — $2.48B → $3.74B
Organizations expose hundreds of APIs and microservices—each a potential attack vector. Traditional network firewalls can’t inspect application-layer attacks like SQL injection, cross-site scripting, or API abuse. Modern WAFs use machine learning to differentiate legitimate user behavior from attack traffic without blocking customers. Getting that balance right is harder than it sounds.
14. Encryption — 10.64% CAGR — $1.35B → $1.98B
NIST’s standardization of quantum-resistant algorithms signals the urgency that organizations can no longer ignore. With quantum computing advances accelerating, encrypted data collected today faces decryption within a decade. Enterprises must transition to post-quantum cryptography now because full integration across complex environments takes years. This isn’t theoretical risk anymore.
15. Security Information and Event Management (SIEM) — 10.30% CAGR — $7.60B → $11.15B
AI transforms SIEM from reactive log collection to proactive threat hunting. The latest platforms embed unsupervised machine learning to detect zero-day attacks and automatically enrich alerts with context. Organizations using AI-powered automation save $1.9 million per breach and cut incident lifecycles by 80 days—turning security operations into a competitive advantage rather than a cost center.
Why this matters
Cloud complexity has proven exponential. With 79% of organizations using multiple cloud providers and managing hundreds of accounts, manual security processes break under the load. The 29.36% CAGR for CSPM isn’t market optimism. It’s organizational survival.
Shadow AI joins shadow IT as a core threatscape element. Shadow AI breaches cost $4.63 million—$670,000 more than standard incidents, according to IBM data. But AI also powers the best defenses, with automated security tools reducing breach lifecycles by 80 days. The same technology that creates vulnerabilities offers the most effective countermeasures.
Compliance costs keep accelerating. Between GDPR, CCPA, and emerging global regulations, manual compliance processes create escalating liability. Automated platforms turn regulatory requirements into competitive advantages by reducing fine exposure and accelerating data subject request responses.
Bottom Line
The organizations winning this transformation aren’t those with the largest security budgets. They’re the ones investing in the right categories at the right time. These fifteen segments define what modern security architecture looks like and capture nearly half of all new security spending through 2029.
Gartner’s 4Q25 data delivers a clear message. Security spending is shifting to automation-driven, zero-trust, cloud-native architectures. Organizations still relying on legacy approaches aren’t just falling behind. They’re accepting risks the market has already priced as unacceptable.
