Gartner's Hype Cycle for Application Security 2026 (published July 21, 2026, by analyst Dionisio Zumerle) identifies three trends reshaping the field: securing the agentic development lifecycle, securing AI agents and applications, and streamlining DevSecOps.
AI Runtime Defense sits at the Peak of Inflated Expectations with High benefit and 5-20% market adoption. NeuralTrust is named as a sample vendor in that category.
Guardian Agents and MCP Cybersecurity are new high-benefit entries On the Rise. Gartner projects that by 2027, 30% of application security exposures will stem from agentic coding, and that through 2029, over 50% of successful attacks against AI agents will exploit access control flaws.
TL;DR - Key Takeaways
- Three trends drive the 2026 report: securing the agentic dev lifecycle, securing AI agents, and streamlining DevSecOps.
- NeuralTrust is named as a sample vendor for AI Runtime Defense, which is At the Peak with High benefit rating and 5-20% enterprise adoption.
- Guardian Agents are On the Rise with High benefit and less than 1% adoption: Gartner considers them Emerging.
- MCP Cybersecurity is a new entry that replaced "Model Context Protocol" on the Hype Cycle, reflecting a shift from protocol adoption to securing the protocol itself.
- Gartner removed AI Gateways from the Hype Cycle to refocus on innovations central to application security. Those functions now map to AI Runtime Defense and MCP Cybersecurity.
- Strategic planning assumptions: 30% of app security exposures from agentic coding by 2027; 40% of orgs relying on AST vendors for AI autoremediation by 2027; 50%+ of AI agent attacks exploiting access control through 2029.
What the 2026 Hype Cycle Shows
On July 21, 2026, Gartner published its annual Hype Cycle for Application Security. The author is Dionisio Zumerle, VP Analyst at Gartner. The report (research ID G00846821) covers more than 20 innovations, from established capabilities like Cloud-Native Application Protection Platforms to early-stage entries like Guardian Agents.

The 2026 edition marks a clear break from prior years. Application security is no longer just about protecting code and APIs. It now must address how AI agents write code, how those agents behave at runtime, and how the protocols those agents use, especially the Model Context Protocol (MCP) can be exploited.
Gartner organizes the 2026 report around three trends.
)
Trend 1: Securing the Agentic Development Lifecycle
Agentic coding tools now write, review, and deploy code with minimal human input. Gartner expects this to create a new class of security exposure.
Its planning assumption: by 2027, at least 30% of application security exposures will result from errors and misconfigurations in agentic coding practices.
The report introduces Agentic Coding Security as a new Hype Cycle entry. It replaced "vibe coding" from the 2025 report: a sign that Gartner views AI-assisted development as a permanent part of the SDLC, not a passing trend. Agentic Coding Security carries a High benefit rating and sits in the 5-20% adoption range.
Agentic AST (Application Security Testing) earns the highest possible benefit rating: Transformational. It sits at 1-5% adoption, meaning the market is early but the payoff is considered significant. Gartner's second planning assumption reflects this: through 2027, at least 40% of organizations will rely on their AST vendors as the default providers of AI-based autoremediation for vulnerable code.
Both entries signal that the tooling security teams use to test and fix code will itself become agentic.
Trend 2: Securing AI Agents and Applications
This is the trend most directly relevant to organizations running production AI systems today.
AI Runtime Defense sits At the Peak of Inflated Expectations: the highest-visibility point on the Hype Cycle curve. It carries a High benefit rating and 5-20% enterprise adoption. The category covers real-time inspection, policy enforcement, and threat detection for AI applications and agents in production.
NeuralTrust is named as a sample vendor in this category, alongside Akto, Check Point Software Technologies, F5, HiddenLayer, Lasso, Noma Security, Pillar Security, SentinelOne, and TrojAI.
NeuralTrust's AI runtime defense capabilities include session-aware security that detects multi-turn attacks, per-route policy enforcement, and native inspection of model inputs and outputs — the core functions Gartner describes for this category.
Guardian Agents are On the Rise with High benefit and less than 1% adoption. Gartner classifies them as Emerging in maturity. A guardian agent is an AI agent that monitors, governs, or takes corrective action on other AI agents. Enterprises deploying multi-agent systems need a way to enforce policies at the agent layer, not just the API or model layer. NeuralTrust's agent posture management gives security teams visibility into what agents are doing and the ability to enforce behavior policies across a fleet.
MCP Cybersecurity is a new entry that replaces "Model Context Protocol" on the Hype Cycle. Last year, the focus was on adopting MCP. This year, it is on securing it. MCP servers expose tools, data, and capabilities to AI agents. Gartner now recognizes that MCP connections are an attack surface: tool definitions can be poisoned, tool calls can be hijacked, and access control over which agents can call which tools is often absent. MCP Cybersecurity carries a High benefit rating with 5-20% adoption.
NeuralTrust TrustGate ships a catalog of over 200 MCP servers with per-consumer governance, per-tool access control, and native inspection of tool definitions for prompt injection, the exact capabilities that sit under the MCP Cybersecurity category.
AI Agent Identity is also On the Rise. It addresses a gap that most AI deployments have today: agents often share credentials, lack unique identities, and cannot be audited at the individual agent level. Gartner rates this High benefit with 5-20% adoption. TrustGate propagates consumer identity through every LLM call and MCP tool invocation, tying each action to an auditable identity.
Trend 3: Streamlining DevSecOps
The third trend is less about new tools and more about making existing ones work together. Application Security Posture Management (ASPM) is Sliding into the Trough of Disillusionment. Reachability Analysis is Climbing the Slope. AI Code Security Assistants are On the Rise.
The common thread: security teams are overloaded with alerts and findings they cannot action fast enough. LLM-driven vulnerability discovery is beginning to generate more findings than humans can triage. The teams that win will be those that automate triage, prioritization, and remediation, not those that find more vulnerabilities.
What Left the Hype Cycle
Three changes are worth noting.
Gartner removed AI Gateways from the Hype Cycle. The report explains this was to refocus on innovations central to application security. The functions an AI gateway provides (runtime inspection, MCP governance, identity enforcement) are now captured under AI Runtime Defense and MCP Cybersecurity, categories with more precise definitions for security buyers.
Bot Management and Mobile Application Security Testing reached full maturity and exited the Hype Cycle. They are solved problems.
Composable Security APIs were declared obsolete.
Three Numbers That Should Shape Your 2027 Planning
Gartner's strategic planning assumptions in this report are unusually specific.
- 30% of application security exposures will come from agentic coding errors by 2027. If your teams are using AI coding agents today and have not updated your SDLC security controls, this is the most pressing gap.
- 40% of organizations will rely on their AST vendors for AI-based autoremediation by 2027. Developers are not going to manually remediate every finding that agentic tools surface. Autoremediation closes the loop.
- 50%+ of successful attacks against AI agents through 2029 will exploit access control. This is the clearest signal in the report. Agents have broad permissions. They act on behalf of users. They call external tools. Most organizations have not defined who can do what at the agent layer.
What This Means for Security Teams
The 2026 Hype Cycle confirms that the application security perimeter has moved. It now includes the agents that write your code, the agents that run in production, the tools those agents call, and the identities those agents carry.
Traditional application security tools such as WAFs, SASTs and DASTs were built for a world where humans write code and APIs serve requests. That world still exists. But it now coexists with a world where agents act autonomously, call MCP tools, and make decisions at machine speed.
The categories Gartner highlights: AI Runtime Defense, Guardian Agents, MCP Cybersecurity and AI Agent Identity are the coverage gaps most enterprise security teams need to close in the next 12 months.
