For decades, companies have operated on a simple assumption that most internet traffic came from people. That assumption no longer holds.
The latest 2026 Bad Bot Report: Bad Bots in the Agentic Age reinforces a shift that is now impossible to ignore. Automated traffic continues to outpace human activity online, accounting for more than 53% of all web traffic in 2025, up from 51% the year before. Human activity has declined to just 47% and continues to fall.
This is not a short-term spike driven by a specific attack cycle or technology trend. It reflects a structural change in how the internet operates. Increasingly, businesses are not serving customers alone. They are serving machines.
Key Findings From the 2026 Bad Bot Report
- Bots now drive 53% of web traffic. Automated activity has officially overtaken humans online, up from 51% in 2024.
- 27% of bot attacks target APIs. Attackers are bypassing user interfaces entirely to operate directly at machine speed.
- Financial services bear the brunt. The sector accounted for 24% of all bot attacks and 46% of account takeover incidents.
- AI agents are a new category of internet participant. They no longer just scan websites; they retrieve data, execute workflows, and act on behalf of users.
AI Agents and Bots Are Becoming the Default Internet User
Automation has always existed on the internet in the form of search engine crawlers, scripts, and background processes. What has changed is the scale, sophistication, and purpose of that automation.
AI is accelerating this shift. AI-driven bots have surged dramatically, but more importantly, AI agents are now emerging as a new category of internet participant. These systems don’t just scan websites; they interact with them, retrieve data, execute workflows, and increasingly act on behalf of users.
In practice, this means that what looks like a customer interaction may not be a customer at all. It may be an AI system querying pricing data, completing a transaction, or testing application behavior. For businesses, this blurs a fundamental line. The distinction between legitimate and malicious traffic is becoming harder to define, because both now operate through the same systems, use the same interfaces, and follow the same logic.
The Rise of Uncontrolled Automation
The real risk is not the presence of bots, but that much of this automation is unmanaged. In earlier phases of the internet, bot activity was episodic and often easier to identify. Today, automation is persistent. It operates continuously across digital services, often indistinguishable from legitimate use. This creates a new category of risk that many organizations are not yet equipped to handle. Uncontrolled automation can distort business metrics, inflate infrastructure costs, degrade performance, and expose sensitive workflows.
For example, bots can continuously query pricing or availability systems, creating artificial demand signals. They can interact with promotional systems at scale, exploiting business logic in ways that traditional security controls are not designed to detect. Even benign automation, when left unmanaged, can place sustained load on systems that were designed for human behavior.
The result is that companies are increasingly sharing their digital infrastructure with automated agents that they neither fully understand nor control.
APIs and Identity Systems Sit at the Center of Modern Risk
As automation evolves, so do attacker strategies. The traditional model of targeting websites at the surface level is giving way to a more direct approach.
Bots are increasingly interacting with the same APIs that power core business functions, including authentication, payments, search, and inventory systems. In 2025, 27% of bot attacks targeted API endpoints, allowing attackers to bypass user interfaces entirely and operate at machine speed. These interactions often appear legitimate, with well-formed requests and successful authentication, but the difference lies in intent and scale.
This is particularly visible in sectors where digital transactions are tightly linked to revenue. Financial services, for example, accounted for 24% of all bot attacks and 46% of account takeover incidents. The goal is not disruption for its own sake, but direct monetization.
In this environment, identity systems are no longer just a security layer. They are a primary point of exposure.
How AI Agents Are Quietly Rewriting Business Models
The shift toward machine-driven interaction is not only a security issue. It is beginning to reshape how businesses operate.
If a growing share of traffic is automated, then traditional metrics such as user engagement, conversion rates, and demand signals become harder to interpret. A spike in traffic may not indicate customer interest. A drop in performance may not be caused by user behavior.
At the same time, AI-driven systems are creating new forms of demand. Companies are beginning to consider how and whether to allow AI agents to access their services, and under what conditions. This raises questions about access control, pricing, and even monetization.
Some organizations are exploring models where AI-driven access is authenticated, measured, and potentially governed as a distinct channel. While still early, this points to a future in which businesses must actively manage not just who accesses their systems, but what.
From Bot Detection to Automation Control
For years, cybersecurity strategies have focused on detecting and blocking malicious activity. That approach is increasingly insufficient in a world where automation is both pervasive and often legitimate. The more important question is no longer whether traffic is automated, but whether it aligns with business intent.
This shift, from blocking bad bots to governing all automation based on intent, requires a new approach. Organizations must move from viewing bots as anomalies to viewing automation as a fundamental part of their operating environment. That means implementing controls that can distinguish between acceptable and harmful automation, applying governance to how systems are accessed, and designing defenses that can adapt as behavior changes.
In effect, the challenge is becoming one of control rather than detection.
A Machine-Driven Internet
The internet is entering a new phase that’s defined less by human interaction and more by machine-to-machine activity. Automation is no longer a layer on top of digital infrastructure but embedded within it, with significant implications for businesses. Trust, performance, and revenue are increasingly shaped by how well organizations manage automated interaction.
Companies that continue to operate under the assumption that users are human risk misreading their own systems. Those that adapt by understanding, governing, and controlling automation will be better positioned to compete in an internet where machines are not just participants, but the majority.
The shift is already underway. The question for businesses is not whether it will happen, but how they will respond.

Frequently Asked Questions
What is the Imperva Bad Bot Report?
The Imperva Bad Bot Report is an annual industry research report analyzing global automated bot traffic, attack trends, and the impact of malicious bots on websites, APIs, and applications. The 2026 edition focuses on the rise of AI agents and agentic automation.
How much of internet traffic is bots in 2025?
According to Imperva’s 2026 Bad Bot Report, automated bot traffic accounted for more than 53% of all web traffic in 2025, up from 51% the year before. Human traffic has fallen to 47% and continues to decline.
Why are AI agents a cybersecurity concern?
AI agents act on behalf of users, retrieving data, executing workflows, and completing transactions through the same interfaces as humans. This blurs the line between legitimate and malicious traffic, makes traditional bot detection insufficient, and exposes APIs and identity systems to automation that organizations cannot easily distinguish from real users.
Which industries are most affected by bot attacks?
Financial services experience the highest impact, accounting for 24% of all bot attacks and 46% of account takeover incidents in 2025. APIs are the dominant attack surface, with 27% of bot attacks targeting API endpoints across all industries.
