How to Compare Online Proctoring Services
9 minute read - Updated: November 2026
Online proctoring services look similar on a feature page. Most offer a lockdown browser, webcam recording, automated flags and some form of identity check, and most integrate with the major learning management systems. The differences that matter show up in three places: what the service can see that the others cannot, what it does with what it sees, and what it costs the student in friction and the institution in privacy exposure. This guide gives you ten criteria, the question to ask under each, and a demo script that settles the comparison faster than a spreadsheet.
1. What it can see
Ask where the service's visibility ends. Browser-only services see the exam window. Webcam services see the camera frame. Device-level services see the applications and windows on the computer, including AI assistants and overlays that hide from screen capture, remote-control sessions and virtual machines. Ask the vendor to name a threat it cannot detect; a vendor who cannot answer has not thought about it.
2. Prevent, detect, or both
Some services stop the session when a rule is broken; others record and report. You want both, chosen per exam. Prevent for high-stakes exams where the rules are stated. Detect for interviews and for institutions that want evidence rather than an interrupted student.
3. Evidence or verdicts
A flag should be a timestamped event a reviewer can open, not a score that decides the outcome. Ask to see a report. If it reads as a list of events with context, a reviewer can defend it at a hearing. If it reads as a risk score with no way to inspect what produced it, it will not survive an appeal.
4. Identity and biometrics
Ask whether the service uses face recognition (matching a face to an identity) or face detection (checking that a face is present and consistent), what biometric data it stores and for how long, and whether identity features can be turned off. Biometric privacy laws differ by state and country; the answer determines your notice and consent obligations.
5. Integration depth
LTI 1.3 is the minimum. Ask whether the quiz is locked until a session runs, whether results appear where instructors already work (gradebook, grader panel), whether course-level defaults exist, and whether per-student accommodations can be set without disabling monitoring. For assessment platforms, ask for the API documentation and a sandbox.
6. The student's experience
Install size, supported devices, time from launch to first question, what happens when a connection drops, what the consent notice says, and what a student sees when a tool is blocked. Run it yourself on an old laptop before you believe the vendor.
7. Privacy and data handling
Hosting region, retention defaults, whether sessions with no findings can be deleted immediately, subprocessors, whether data trains the vendor's models, and whether video or images go to third-party AI providers. Read the data processing agreement, not the marketing page.
8. Security posture
SOC 2 Type 2 report or examination status, HECVAT, last penetration test, accessibility conformance (VPAT). A vendor mid-examination should say so and give dates.
9. Review workload
Automated flags are only useful if someone reviews them. Ask how many flags a typical session produces, how a reviewer clears a session with no findings, and whether the vendor offers human review as a service for institutions that do not want to staff it.
10. Price structure
Per student per year, per exam, per student per course, or student-pays. Whether human review, live intervention and implementation are separate lines. Whether the service can be bought for the sessions your current tool cannot cover rather than as a full replacement, which is often the cheapest path for an institution with a contract in place.
The demo script
Give the vendor an exam in your LMS and ask them to run it with your staff as students. One student opens a desktop AI assistant. One keeps a phone below the desk. One opens a second monitor. One connects from a virtual machine or through a remote-control tool. One does nothing wrong. Afterward, review the five reports together. The comparison is usually over at that point.
Frequently asked questions
What is the biggest difference between online proctoring services in 2026?
Whether they can see assistance that runs outside the browser and off camera: desktop AI assistants, hidden overlays, remote control and virtual machines.
Do we have to replace our current proctoring tool?
No. Device-level proctoring is usually run alongside a lockdown browser or webcam tool for the sessions it cannot cover.
How should we weigh price?
After detection, integration and privacy. A cheaper service that misses the threats you care about costs more in hearings and in credibility.
Should we trust automated flags?
Treat them as evidence for a person to review. Ask any vendor to show the review workflow before you buy.
What should we ask about AI tools that do not exist yet?
Ask how the service catches a tool by its behavior (hidden windows, process launches, focus changes) rather than by its name.
