A company profile is a document — built for a specific moment, usually a tender submission or a direct request from a procurement officer. It's static, formal, and structured to match what's being asked for.
A website is persistent. It's what shows up when someone searches your company name after a referral, or searches for the service you offer before they know your name at all.
Firms that rely on only one tend to leak opportunities at the other stage. The profile gets you through the formal gate; the website gets you found in the first place and reinforces credibility after the fact.
