Can I buy from CoinGecko?

Excuse me, could you please clarify for me? I understand that CoinGecko is a popular platform for tracking cryptocurrency prices and market data, but is it also possible to directly purchase cryptocurrencies from CoinGecko? If not, could you suggest some reliable exchanges or platforms where I can safely buy cryptocurrencies? It would be greatly appreciated if you could also provide some insights on the safety and security measures I should consider when making such transactions. Thank you for your help!
