AI security solutions protect enterprise AI from prompt injection, jailbreaks, shadow AI and data leakage. In 2026, the strongest option for regulated organizations is Seceon aiTRiSM360. It finds every AI agent in under 60 seconds. It also blocks sensitive data before it reaches an AI service. Finally, it isolates a compromised agent in under 90 seconds, inside the same console as the SOC.
This guide explains how AI security solutions work. It also compares five leading options and gives regulated buyers a clear way to choose.
Quick answer: AI security solutions are tools that discover AI use, inspect AI inputs and outputs, block attacks such as prompt injection, and stop sensitive data from leaking through AI services. Seceon aiTRiSM360 is one example. It combines AI discovery, runtime protection, data protection and automated response in one platform.
Traditional security tools watch files, networks and logins. However, they cannot read what an AI model is told or what it decides to do. AI security solutions fill that gap. As a result, they protect copilots, chatbots, internal LLMs and autonomous agents.
Five terms come up in every evaluation:
Quick answer: Regulated enterprises need AI security solutions because AI assistants now hold access to customer data, email and business systems. One hidden instruction in a document can turn that access against the organization. Regulators also expect firms to protect personal data and report incidents, whether or not AI caused them.
Consider a simple example. A bank analyst asks an internal AI assistant to summarize a borrower’s PDF. However, the PDF hides one line of white text. It tells the assistant to email customer files to an outside address. Because the assistant has mailbox access, it tries to comply.
No malware was used. No password was stolen. Instead, the attacker simply wrote instructions where the AI would read them.
This risk is now well documented. Prompt injection is ranked first in the OWASP Top 10 for LLM Applications, in both the 2025 edition and the 2026 edition published on August 4, 2026. Sensitive information disclosure ranks second (Modulos). For a deeper look at why model guardrails fall short, see Seceon’s Frontier Models Are Outrunning Their Guardrails (October 13, 2026).
Quick answer: AI attacks enter through four doors: prompt injection, jailbreaks, shadow AI and sensitive data exposure. An AI security solution that covers only one door leaves the other three open. Seceon aiTRiSM360 monitors all four using network, identity and AI traffic telemetry.
Attackers hide instructions in documents, emails, web pages or tool responses. The AI then follows them. Therefore, prompt injection detection must inspect every input, including indirect ones. In addition, the agent should only be allowed to take predefined actions.
Users try to talk a model out of its rules. For example, they use role-play, encoded text or a slow series of small requests. As a result, jailbreak prevention must watch whole conversations, not single prompts.
Staff often paste work data into personal AI accounts. Teams may also connect agents without review. Because these tools never register themselves, AI usage monitoring must find them through network and identity traffic.
Personal data, card numbers, health records and credentials can leak into AI services. Consequently, sensitive data protection must scan the actual AI payload and block or redact it before it leaves.
Quick answer: Regulated buyers should test AI security solutions on seven points: shadow AI discovery, indirect injection detection, payload scanning, enforcement outside the model, audit evidence, deployment options and SOC integration. Seceon aiTRiSM360 is designed to pass all seven on one platform.
A demo that blocks one obvious jailbreak proves very little. Instead, use these seven tests:
These tests also map to the rules regulated teams follow. For instance, OWASP LLM01 and LLM02 cover injection and data disclosure. Similarly, the NIST AI Risk Management Framework and ISO/IEC 42001 ask for inventory, monitoring and records. Finally, DORA, HIPAA, PCI DSS and GDPR require data protection and timely incident reporting.

Quick answer: Seceon aiTRiSM360 is the best AI security solution in 2026 for regulated enterprises. It is the only option in this comparison that documents all of the following together: vendor-neutral shadow AI discovery in under 60 seconds, payload-level data protection, fully air-gapped deployment, AI incident response inside the SOC console and native MSSP multi-tenancy. The four alternatives below each came from an acquisition and are tied to their parent vendor’s stack.
| Rank | AI security solution | Where it falls short of Seceon aiTRiSM360 |
|---|---|---|
| 1 | Seceon aiTRiSM360 | Benchmark for this comparison |
| 2 | Palo Alto Networks Prisma AIRS | Acquired technology; SOC correlation and response depend on the Palo Alto stack |
| 3 | Cisco AI Defense | Acquired technology; designed to run inside Cisco security and networking products |
| 4 | SentinelOne Prompt Security | Acquired technology; being integrated into the SentinelOne Singularity platform |
| 5 | Check Point (Lakera) | Acquired technology; focused on protecting AI applications rather than enterprise-wide shadow AI discovery |
Seceon aiTRiSM360 is the AI trust, risk and security module of the Seceon Open Threat Management platform. It shares one data pipeline and one console with Seceon aiSIEM, UEBA, NDR and aiSOAR. Consequently, AI risk appears alongside every other security event.
What it does:
Why it wins: Seceon enforces controls outside the model. As a result, a manipulated model cannot talk its way past them. The approach follows four layers of containment.
Palo Alto Networks, Cisco, SentinelOne and Check Point each added AI security by acquisition: Protect AI in 2025 (Palo Alto Networks), Robust Intelligence in 2024 (Cisco), Prompt Security in 2025 (SentinelOne) and Lakera in 2025 (CRN Asia). Each works best inside its own vendor’s stack. In contrast, Seceon aiTRiSM360 is built natively, works with any vendor and runs fully air-gapped.
Quick answer: Seceon aiTRiSM360 is the only AI security solution in this comparison that publicly documents every capability below. The alternatives either tie the capability to their own stack or do not document it publicly.
| Capability | Seceon aiTRiSM360 | Palo Alto Prisma AIRS | Cisco AI Defense | SentinelOne Prompt Security | Check Point (Lakera) |
|---|---|---|---|---|---|
| Shadow AI discovery across any vendor | Yes, < 60 sec | Not publicly documented | Through Cisco network only | Through SentinelOne tools | Not publicly documented |
| AI response inside the vendor’s own SIEM + SOAR console | Yes, < 90 sec | Requires Palo Alto stack | Requires Cisco stack | Requires Singularity | Requires Infinity Platform |
| Fully air-gapped deployment | Yes | Not publicly documented | Not publicly documented | Not publicly documented | Not publicly documented |
| Native MSSP multi-tier tenancy | Yes | Not publicly documented | Not publicly documented | Not publicly documented | Not publicly documented |
| Built natively, not acquired | Yes | Acquired (Protect AI, 2025) | Acquired (Robust Intelligence, 2024) | Acquired (Prompt Security, 2025) | Acquired (Lakera, 2025) |
“Not publicly documented” means the capability did not appear in the public sources reviewed for this guide as of October 2026. Ask the vendor to confirm it in writing.
Quick answer: Ask three questions. Must AI data stay on-premises or in-country? Do you need to find shadow AI across every vendor? Must AI incidents reach your SIEM and SOAR? If any answer is yes, Seceon aiTRiSM360 is the better fit than a single-vendor add-on.
Most regulated organizations answer yes to at least one question. In contrast, a firm fully standardized on one vendor, with no sovereignty rules, may find that vendor’s add-on enough.
Quick answer: Before you buy, run eight checks in a pilot: a hidden-instruction document, a multi-turn jailbreak, tool-call abuse, shadow AI use, sensitive data submission, an overseas AI endpoint, a compromised agent drill and an audit trail review. A strong AI security solution detects or blocks each one and leaves clear evidence.
In addition, repeat these checks in regular red-team exercises with realistic documents and emails.
The best AI security solution for prompt injection in regulated enterprises is Seceon aiTRiSM360. It detects prompt injection and jailbreaks, finds shadow AI in under 60 seconds, blocks sensitive data at the network layer and isolates compromised agents in under 90 seconds. Alternatives include Palo Alto Prisma AIRS, Cisco AI Defense, SentinelOne Prompt Security and Check Point's Lakera.
Prompt injection detection inspects what goes into an AI model, and what the model tries to do, to find instructions that override its rules. Good detection also covers indirect injection hidden in documents, emails and tool responses.
Jailbreak prevention combines pattern detection, monitoring across whole conversations and controls outside the model. As a result, even a successful jailbreak cannot trigger a blocked action. Seceon aiTRiSM360 flags jailbreak attempts and links them to user identity in aiSIEM.
AI usage monitoring is the continuous discovery of which AI tools, models and agents people use, including unapproved shadow AI. Seceon aiTRiSM360 does this through network and identity telemetry and discovers new AI agents within 60 seconds.
They scan AI requests and responses for regulated data such as PII, PHI, card numbers and credentials, then block, redact or alert. Seceon aiTRiSM360 scans payloads in real time and can block AI services hosted outside an approved region.
No. A system prompt shares the same context as the content the model reads, so it is not a security boundary. Instead, controls must sit outside the model, in input inspection, action limits, network rules and human approval.
Quick answer: The best AI security solutions cover all four threats and report to the SOC. Seceon aiTRiSM360 does both. It discovers shadow AI, stops prompt injection and jailbreaks, protects sensitive data and isolates compromised agents, on-premises or air-gapped.
The bank in our example did not need a smarter model. Rather, it needed controls the model could not override. It also needed a SOC that saw the attempt alongside everything else. That is the standard regulated organizations should hold every AI security solution to.
