Chatbot security for small businesses
Varselio is a Swedish security service that checks what your website chatbot or AI agent is about to say or do, in real time, and stops prompt injection, jailbreaks and data leaks before they cause harm, asking a human before risky actions.
Why small businesses are exposed
An AI chatbot on your website answers customers around the clock. If it can look up orders, see customer details or trigger refunds, a visitor who tricks it can get the same access. Small businesses rarely have a security team watching, so a problem can go unnoticed for a long time.
The main risks
- Prompt injection and jailbreaks: a visitor talks the bot into ignoring its rules.
- Data leaks: the bot hands out customer details, internal documents or keys.
- Costly actions: refunds, discounts, deletions or messages sent in your name.
Simple steps you can take today
- List what your chatbot can see and do, and remove anything it does not need.
- Never put passwords, API keys or private documents in the bot's instructions.
- Make anything involving money or customer data wait for a human.
- Read through the bot's conversations now and then, or get alerts for blocked attempts.
How Varselio fits a small business
- Free to start, no card needed. Prepaid passes from 279 SEK incl. VAT, and nothing renews automatically (see pricing).
- No security team needed: dangerous messages and actions are stopped automatically, and risky ones wait for your yes on your phone.
- Little setup: whoever built your bot pastes in one short snippet, or ask for a free pilot and get help.
- Your data stays in the EU and is never sold or used to train AI models.
- A person answers: you talk directly to the founder.
About prompt injection (OWASP LLM01)
Prompt injection is number one on the OWASP Top 10 for LLM applications: LLM01:2025 Prompt Injection. OWASP notes that it is unclear whether fool-proof prevention exists, and recommends layered measures such as input and output filtering, least privilege and human approval for high-risk actions.
Varselio reduces risk, but no security product is 100% secure: it cannot guarantee that every harmful message or action is detected.
