The level of autonomy and intelligence AI agents bring is definitely remarkable and worth the hype. But what is often missed are the challenges that come with its deployment. A real-life example of how AI and AI agents implementation can go wrong is Klarna.
The popular Swedish fintech company replaced its 700 workers with AI to achieve cost-efficiency and innovation. What they achieved in reality was an increase in customer complaints, frustrated users, and mismanaged operations.
If you are planning to deploy an AI agent for any business use case, it is a must to get a detailed idea of the challenges that may become a roadblock to the successful deployment. This blog highlights AI agent deployment challenges along with how to overcome or prevent them.
What Are AI Agents and Why They Matter
Let’s begin with the basics. AI agents are autonomous software systems that perceive inputs or understand the environment to make decisions and take actions. All this is done without any manual intervention; yet, the agents successfully achieve the given objective. AI agents observe, plan, act, learn, and refine.
Why they matter
In short, AI agents matter because they bring a revolutionary change in how organizations work, run their operations, or deliver services. In 2026, organizations from healthcare, travel, finance, e-commerce, manufacturing, real estate, and other industries are investing in AI agents for one or more reasons that have been given here:
- Productivity Gains
- Cost Optimization
- Round-the-Clock Operations Execution
- Seamlessly Scale
- Faster Decision-making
- Enhance Customer Experience
- Automating Repetitive Business Operations

6 Critical Challenges in Deploying AI Agents
There is no doubt that AI agents deliver transformative benefits, but their deployment comes with complex challenges that can impact implementation, inflate costs, and even lead to compliance-related risks. Understanding these challenges before beginning with the development or even deployment of AI agents is highly crucial to designing a successful roadmap. Let’s dig deeper into the top six AI agent deployment challenges:
- Cost
Gartner anticipates that over 40% of AI agents or Agentic AI projects will be cancelled by 2027. One major reason for this is escalating costs. Let’s understand this one of the biggest AI agent deployment challenges in detail.
AI agents operate in loops rather than just responding once per request. So, if there is just one task, it is quite common for an agent to trigger multiple steps, tool calls, and API interactions.
Every step needs tokens, computational power, and infrastructure resources. Token-based interface cost is visible and can be calculated. However, this cost is just a fraction of the total cost needed to deploy agents.
Deploying AI agents in every workflow may increase the number of tokens, which can further add unnecessary complexity to the process. A simple query may cost somewhere between $0.01 – $1.00/interaction, whereas complex reasoning may cost $1 – $50 per minute.
Why is cost a challenge
- Token consumption, hence the cost, varies depending on the complexity of the query.
- An agent that is not configured properly may generate unnecessary API calls to continuously increase the costs.
- Inability to measure the actual business value vs. operational cost.
- Uncertain infrastructure overheads.
- Training, fine-tuning, testing, and monitoring the AI agent are those costs that are not clearly visible or often get missed while calculating the total cost of AI agent deployment.
- Security
Security is one of the critical challenges in deploying AI agents, mainly those with complete authority to take actions autonomously. These agents can even share sensitive or confidential information, as they often rely on emails, chat messages, API calls, tickets, and other external inputs to trigger actions.
Security challenges in AI agent deployment can be understood with this example. An agent ( designed to autonomously respond to emails) gets an email asking to provide confidential information about the company; without an efficient security mechanism, it may provide the same.
Why is security a challenge
- The agent may fail to verify the sender’s identity before responding and may treat malicious instructions as legitimate business requests.
- Lack of role-based access control at the action level.
- Missing approval checkpoints for high-risk actions, such as sharing the company’s confidential sales or revenue details.
- The agent may execute actions that violate internal security policies.

- Safety
A report by Gartner highlights that approximately 33% of enterprise software applications will have agentic AI capabilities by 2028. Safety becomes a critical challenge in this situation as most organizations grant broader access to the agents to enable them automate as many operations as possible.
Safety means the agent operates within acceptable limits and doesn’t cause any harm to the organization, even when there is no external threat involved. Let’s understand this with this example:
Why is safety a challenge
- Over-permissioned agents lead to unintended actions
- Lack of business context causes unsafe decisions
- Absence of action-level guardrails
- Compliance
Organizations that don’t clearly define the processes or departments where agents should be deployed, what actions they can take, and which workflows need human oversight may face compliance challenges in AI agent deployment.
In regulated environments, it is a must for every agent to take actions as per the predefined rules about information accessibility and sharing, and action taking. Since AI agents operate across multiple systems, they may fail to comply with regulations (CCPA, HIPAA, GDPR, etc.), resulting in the sharing or revealing of sensitive data or information.
Why is compliance a challenge
- Decision-making happens inside model reasoning
- AI agents may capture outcomes but not intent
- Action chains of AI agents span multiple systems

- Operational Complexities
Implementing multiple agents to work with different enterprise systems and make decisions in real time can be challenging. Agents working with multiple systems (ERPs, CRMs, payment gateways, internal APIs, third-party services, etc.) means increased dependencies and complexities. Also, if one system fails, it may impact the entire workflow.
Besides, AI agents maintain contexts across sessions, resume tasks after a delay, and operate for hours and even days. Just in case the agent loses context or resumes working from an incorrect state, it may start repeating actions and skip critical validation steps.
The agent may even act according to outdated or partial information. Other operational complexities may also arise due to API timeouts, model errors, and external system unavailability.
When the challenges occur
- Controlled retries are not defined.
- Checkpoints are not implemented.
- Rollback strategies are not defined.

- Testing
As the agents’ behavior cannot be determined and is context-driven and influenced by external data sources, they cannot be tested like traditional AI systems or solutions. Another reason making testing difficult is that the agents learn and adapt automatically over time.
It means that the agent that was working perfectly from the beginning may not perform with the same capabilities after an update. They also have to work with complex multi-step workflows. Inadequate testing may cause deploying agents to silently drift into unsafe or non-compliant behavior.
Why is testing a challenge
- It is difficult to create realistic test datasets that are similar to production
- Not being able to create all scenarios to simulate malicious actors or edge cases
- Difficulty in measuring non-functional requirements.
- Ensuring continuous testing as models and systems evolve.

Best Practices for AI Agent Deployment
Now that you know the common challenges that can become roadblocks to the successful implementation of AI agents in your organization, it’s time to explain practices you can follow to avoid these AI agent deployment issues. Let’s quickly take a look at these AI agent deployment best practices:
- Optimize Costs
As explained earlier, the cost of AI agents can increase without efficient management. Every interference, retry, and action taken by the agent multiplies the cost. Here are a few best practices you can follow:
- Avoid deploying LLM-powered agents for tasks that require following a specific rule.
- Choose task-specific models over large LLMs.
- Set clear boundaries for execution, including iteration and retry limits.
- Measure ROI at the business-process level or cost per workflow to find out agents that are not performing.
- Verify Actions for Security
Security is a challenge as the agents operate on external inputs sent by anyone, including authorized and unauthorized persons. Here is what you need to do to amplify security:
- Train your agent to treat all external inputs as untrusted unless the sender’s identity and context & intent of the query are validated and verified.
- Implement explicit authorization checks to enable the agent to authenticate before taking high-impact actions.
- Restrict the permissions you give to the agent to perform tasks.
- Ensure human oversight to flag unexpected actions and unusual decision patterns of the agent.
- Define Safety Protocols
Best practices to ensure the safety of the AI agent seem quite similar to those of security. That’s because safety issues also arise when the agent responds to the queries asked by even unauthorized persons. Here are some practices to follow:
- Define clear actions and boundaries for the agent.
- Mandate manual approvals for actions that involve confidential information or compliance checks.
- Implement confidence and context checks to ensure the agent acts only when input crosses predefined boundaries.
- Keep a tab on the situations where the agent made incorrect decisions. Improve guardrails to fix this.
- Make Governance a Part of the Architecture
Compliance-related challenges mostly occur due to poor architecture. Therefore, do the following to avoid them:
- Embed strict compliance rules when defining agent workflows. This will make the agent ensure policy checks before taking any action.
- Keep a record of inputs, decisions, and actions taken by the agent. Review them from time to time.
- Add additional verification layers for sensitive actions, such as OTP submissions, payments, or data sharing.
- Align agents with data governance policies.
- Ensure Operational Resilience
Make sure the agents don’t cause a system-wide disruption. Follow these practices:
- Implement strict checkpoints and rollback mechanisms to ensure the actions of the agent can be reversed or stopped during execution to prevent the sharing of sensitive information.
- Ensuring the efficient management of dependencies, retries, and sequencing across agents and systems.
- Track decisions, execution paths, and errors made by the agent to ensure fast troubleshooting.
- Use Sandbox Environments for Testing
Traditional QA methods don’t work in situations where the agent has to make real-time decisions and act autonomously. Keep the following in mind to avoid testing-related challenges that occur during agent deployment:
- Test agents in real-world environments and adversarial scenarios.
- Validate the defined boundaries by testing the agents in situations where they are not supposed to take action or respond to share sensitive information.
- Use sandbox environments to ensure safe experimentations to ensure it will not impact production systems.
- Conduct re-testing and re-validation after model updates or system integrations.
