The Data Protection Gateway, Identity Gateway and API Gateway operate as a unified layer that governs access, enforces protection and controls what cloud, third-party and AI applications can see.

About Cequence Security

Cequence Security sells a single platform that combines agentic AI governance, API security, bot defense and web app protection. Cequence says the platform welcomes legitimate traffic and shuts out abuse.[5]

Cequence says its platform gives organizations the security, governance and control they need to protect their applications and data against attacks, business logic abuse and fraud. Cequence says that core technology now extends to securing the AI agents and workflows modern enterprises depend on.[6]

Cequence analyzes behavioral intent so good agents transact smoothly while fraud, abuse and account takeover are kept at bay. Cequence says the platform distinguishes humans and bots, and legitimate automation from threats. Cequence says the platform continuously evaluates live traffic to identify threats in real time and trigger countermeasures. Cequence says its detection runs independent of the client. Cequence also says customers do not need to replace their CDN, because Cequence is separate from the delivery network.[5][6]

Cequence API Security is an AI-first solution that discovers, monitors and tests APIs. Cequence API Security assesses a broad range of risks that can lead to compliance or governance issues, data loss and business disruption. Cequence API Security discovers internal, external and third-party APIs. Cequence integrates with existing infrastructure such as API gateways, or can be deployed inline. Cequence identifies and masks sensitive data using ML-based rules with predefined and customizable data patterns. Cequence API Security test plans can be generated automatically from Postman collections or API specifications. Cequence API Security exposes every capability as MCP tools.[7]

Cequence AI Gateway contains every agent wherever it runs and governs its actions in real time, across any model, MCP server, API or application, at enterprise scale. Cequence says its Agent Personas scope every agent to the tools, APIs, skills and LLMs its job requires. Agent Behavior Protection evaluates each tool call in the context of the full session. Agents authenticate with Agent Access Keys while the gateway brokers backend tokens, so agents never have direct access to backend credentials. Prompt Guard detects prompt injection, override instructions and safety filter bypass attempts before they reach a model or tool. Cequence AI Gateway can monitor, redact and block sensitive data across more than 100 out-of-the-box detection types. Budgets in Cequence AI Gateway cap spend per employee, team and agent persona, by day or by month. Trusted registries of MCP servers, APIs, LLMs and skills define exactly what agents can connect to.[8]

Cequence takes a network-based approach that monitors all API transactions to protect against AI bot attacks, IP scraping and sensitive data exposure. Cequence says its approach requires no application modification. Cequence discovery identifies and inventories all APIs in use, whether they are internal, external or third-party. Cequence actively monitors API transactions, including GenAI and agentic AI APIs, for inappropriate sensitive data flows. Cequence describes business logic abuse as targeting the intended functionality of applications and APIs rather than exploiting traditional technical vulnerabilities. Cequence says it protected multiple major telecommunications companies from a series of six high-profile BOLA API attacks.[9][10][11]

Cequence describes use cases that include stopping credential stuffing and brute force attacks before attackers seize legitimate user accounts. Cequence describes use cases that include neutralizing scalper bots that buy out high-demand inventory before real customers can. Cequence describes use cases that include blocking bots that enumerate account numbers and drain gift card and rewards balances. Cequence describes use cases that include identifying and redacting PII, credentials and regulated data moving through API traffic in real time. Cequence says PCI DSS v4.0.1 includes provisions that require capabilities found in Cequence API Security and Bot Management, including API discovery and sensitive data identification and masking. Cequence describes digital banking platforms, mobile apps, payment systems, trading portals, partner integrations and open banking initiatives as relying on interconnected APIs to move money and data in real time.[1][3][5][6][7][12][13][14]
