Reviews

What candidates say after passing

★★★★★

Incident response sequencing is where I consistently lost points - I kept eradicating before containing.Edureify AI ran me through enough containment-first scenarios that the correct order became automatic. That alone probably accounted for 8–10 questions.

Oliver B.

Delivery Manager

★★★★★

I confused IDS and IPS in every practice test for the first two weeks.Edureify AI's paired scenario approach - same threat, IDS response vs. IPS response - locked in the distinction in a way definitions never did.

Amira S.

Risk Manager

★★★★★

The social engineering taxonomy questions are deceptively specific. Knowing phishing from spear phishing from whaling from vishing - and what distinguishes each - requires scenario exposure, not just reading. The platform's variety of attack-type scenarios made this automatic.

Vikram T.

IT Director

★★★★★

Performance-based questions on SY0-701 are harder than the multiple-choice.Edureify AI's scenario reasoning practice transferred directly to PBQ performance - I approached each one with a structured elimination method rather than guessing under pressure.
