Kavra LabWhat bot detection software does
Bot detection software decides whether a visit comes from a real person, a good bot such as a search crawler, an AI agent, or automation pretending to be a browser. The good products do this without showing puzzles to real customers, and they return a decision fast enough to act on at the moment it matters.
Two product types dominate. Edge bot management runs inside a CDN, proxy or web server module and enforces allow, block or challenge before a request reaches your application. In-app risk platforms collect signals from the page and your backend, then return an assessment that your own code acts on. Many large sites use both: one filters volume at the edge, the other judges high-value actions like account takeover attempts, credential stuffing and multi-accounting.
How to evaluate bot detection software
Use these criteria in every vendor call. Ask for answers on your own traffic, not a demo dataset.
| Criterion | What to ask | Why it matters |
|---|---|---|
| Deployment | Does it need a CDN, proxy, DNS change or server module, or only a script and an API call? | Decides time to value and who in your team owns it |
| Who decides | Does the vendor enforce, or does your backend receive a verdict? | Fraud decisions often need business context the vendor lacks |
| Explanations | Can an analyst see why a visit was flagged, in plain words? | Unexplained blocks are hard to defend to customers and support |
| Evasion coverage | How does it handle antidetect browsers, residential proxies, emulators and stealth automation? | Serious attackers use these tools by default |
| Account-level view | Can it link many accounts to one actor and compare a login with the account's history? | Bonus abuse and takeover are about people, not single requests |
| Friction | When does a real user see a challenge, and what kind? | Every visible challenge costs conversions |
| AI agents and good bots | How are verified crawlers and agents recognized, and can you set policy per agent? | Agentic traffic is growing, and not all of it is hostile |
| Testing | Is there an observe-only or monitor mode before blocking? | You need to measure false positives before they hit customers |
| Privacy | Is a legal basis applied per region, and is data kept separate per customer? | GDPR and consent rules apply to device signals |
| Scope | Which extra products come with it: WAF, DDoS, ad fraud, waiting room? | A suite can replace several tools, or add ones you do not need |

Edge bot management vs an in-app risk platform
In-app risk platform
- Script plus API call, no routing change
- Verdict goes to your backend with reasons
- Links accounts and compares logins with history
- Decision uses your business context
Edge bot management
- Runs in a CDN, proxy or server module
- Blocks before traffic reaches your origin
- Often bundled with WAF and DDoS protection
- Vendor or edge rules enforce the decision
Which type of product is the better fit
Match the product type to where your problem lives. None of these is right for everyone.
- Your traffic already runs through a large CDN and your main problem is volume (scraping, floods, inventory bots): an edge product from your CDN or security vendor is often the simplest start.
- You want enforcement handled for you with minimal tuning: a managed bot defense product that decides at the edge or proxy fits that goal.
- Your losses come from accounts (bonus abuse, fake signups, takeover, free-trial farming): you need account linking and explained verdicts at signup and login. That is where Kavra is built to help.
- You run a large advertising program: look at vendors with a dedicated ad fraud product. Kavra does not cover ad fraud.
- You need a waiting room, WAF or DDoS protection in the same contract: a broad security suite may cover more of your list.
- Procurement requires long enterprise track records: established vendors with published references will fit that process more easily.
How to run a bot detection trial
- 01
Pick two or three flows
For example signup, login and checkout. Measure the current fraud rate and review cost on each.
- 02
Run in monitor mode
Deploy each candidate without blocking, on the same traffic, for at least two weeks.
- 03
Review disagreements
Where tools disagree, have an analyst check the sessions. That is where accuracy and explanations show.
- 04
Check friction
Count how often real customers would have seen a challenge under each tool's recommended policy.
- 05
Decide and phase in
Start with a cautious policy on one flow, then widen as false positives stay low.
