Introduction: The New Cybersecurity Battlefield Begins Inside Artificial Intelligence
Artificial intelligence is rapidly becoming a powerful operational force inside companies, controlling workflows, analyzing sensitive information, and making automated decisions. However, as AI agents become more independent, cybersecurity experts are warning that a new generation of threats is emerging. These systems can be manipulated, misdirected, or abused in ways that traditional security tools were never designed to handle.
Tenet Security, a new cybersecurity company founded by former leaders from Cisco AI Defense initiatives, has officially exited stealth mode with $6 million in seed funding. The company aims to protect AI agents while they are actively running, preventing dangerous behavior such as uncontrolled actions, unauthorized access, and so-called agentjacking attacks.
The announcement highlights a growing industry concern: organizations are deploying AI agents faster than security frameworks can adapt. While traditional cybersecurity focuses on protecting networks, endpoints, and identities, AI security requires monitoring decision-making systems that can independently interact with digital environments.
Tenet Security Targets the Hidden Risks of Autonomous AI Agents
Tenet Security is entering the market with a mission to create runtime protection for artificial intelligence agents. Unlike conventional security solutions that protect systems before deployment, Tenet focuses on observing AI behavior during execution and stopping harmful actions before they cause damage.
AI agents are becoming increasingly capable. They can write code, access databases, communicate with customers, manage business operations, and execute complex tasks without constant human supervision. This autonomy creates a new attack surface where attackers may attempt to manipulate an AI system’s instructions or exploit its permissions.

Former Cisco AI Defense Leaders Build a Security Layer for the AI Era
Tenet Security was created by cybersecurity professionals with experience in artificial intelligence defense. Their background reflects the growing demand for specialists who understand both traditional security challenges and the unique risks created by autonomous machine systems.
The transition from network security to AI security represents a major shift in the cybersecurity industry. Organizations previously focused on protecting servers, applications, and employees. Now they must also secure intelligent systems that can make decisions and perform actions independently.
The company believes AI agents require a dedicated security layer similar to how endpoint protection became essential during the rise of personal computing and cloud security became critical during digital transformation.
Agentjacking: The Emerging Threat Against Artificial Intelligence Systems
One of the primary threats Tenet Security highlights is agentjacking. This concept describes attacks where malicious actors manipulate AI agents into performing actions outside their intended purpose.
An attacker could potentially influence an AI assistant through hidden instructions, compromised data sources, malicious documents, or manipulated external tools. Once controlled, an AI agent with access to company systems could unintentionally expose confidential information, modify important files, or execute harmful operations.
Traditional security systems may fail to detect these incidents because the activity appears to originate from a legitimate AI application. The challenge is no longer only identifying unauthorized users, but understanding whether an authorized AI system is behaving safely.
The $6 Million Seed Funding Shows Growing Investor Confidence in AI Security
Tenet
Companies are rapidly integrating AI into critical business processes, but many organizations lack clear strategies for monitoring AI behavior. This creates opportunities for specialized cybersecurity startups focused on AI governance, protection, and compliance.
The funding will likely help Tenet expand engineering capabilities, develop its runtime security platform, and compete in an increasingly crowded AI security market.
Why AI Runtime Security Could Become the Next Major Cybersecurity Category
Deep Analysis: Linux Commands and AI Security Monitoring
Modern cybersecurity professionals already rely on operating system visibility tools to detect unusual activity. As AI agents become part of enterprise environments, similar monitoring concepts may evolve into AI behavior analysis.
On Linux systems, administrators can investigate running processes using:
ps aux
This command reveals active processes and helps identify unexpected workloads.
Security teams can monitor system activity using:
top
or:
htop
These tools provide real-time visibility into resource consumption and suspicious execution patterns.
Network connections can be reviewed through:
netstat -tulpn
or:
ss -tulpn
These commands help identify unexpected communication channels that could indicate compromised services.
File activity monitoring remains essential through tools such as:
auditctl
and:
ausearch
which allow administrators to track important system events.
For AI infrastructure, these traditional security approaches may evolve into behavioral monitoring systems capable of understanding whether an AI agent is acting within expected boundaries.
The future security model will likely combine identity management, permission controls, behavioral analysis, and automated response mechanisms.
AI agents cannot simply be treated as software applications. They are becoming digital workers with access privileges, decision-making abilities, and operational authority.
A compromised AI agent could represent a different category of threat because the attacker may not need direct access to company systems. Instead, they may manipulate the AI system itself into becoming an internal threat.
Security platforms like Tenet are attempting to solve this problem by creating protective controls around AI behavior.
The cybersecurity industry is moving toward a world where companies must ask not only “Who accessed this system?” but also “Why did this AI system make this decision?”
Runtime security could become a fundamental requirement for organizations deploying autonomous AI technologies.
The same way firewalls, antivirus platforms, and endpoint detection became standard security layers, AI behavior protection may become a necessary component of future enterprise environments.
What Undercode Say:
The rise of AI agents represents one of the biggest changes in cybersecurity history. For decades, security teams have focused on protecting human users, applications, and infrastructure. AI introduces something different: a machine entity that can understand instructions, interact with systems, and independently perform tasks.
Tenet
The danger is not always a hacker breaking into a network. The danger may be an AI agent following manipulated instructions while using legitimate permissions.
This creates a difficult security challenge because traditional detection methods depend heavily on identifying abnormal access patterns. AI-driven attacks may look normal because the system itself has permission to perform the actions.
Future cybersecurity platforms will likely need deeper context awareness. They will need to understand intent, not just activity.
A database query from an employee may be normal. The same database query from an AI agent operating outside its expected mission could represent a serious incident.
AI security will become a combination of cybersecurity, governance, machine learning monitoring, and behavioral intelligence.
The companies that successfully protect AI systems will likely become major players in the next generation of cybersecurity.
However, there are challenges. AI behavior is complex, and defining what is “normal” can be extremely difficult. Businesses may struggle with balancing security controls and AI flexibility.
Too many restrictions could make AI agents less useful. Too few restrictions could create dangerous vulnerabilities.
The future will require a careful balance between automation and control.
Tenet
The next major cyber incidents may not involve stolen passwords or malware alone. They may involve intelligent systems being manipulated into making harmful decisions.
Organizations that prepare early will have a significant advantage as AI becomes more deeply integrated into everyday operations.
