What is the real Uniswap website?

Could you please clarify for me what the official and authentic Uniswap website is? I've noticed several websites claiming to be Uniswap, but I'm concerned about the authenticity of these platforms. It's important for me to ensure that I'm accessing the legitimate and secure website for Uniswap, as I'm interested in exploring its decentralized exchange services. Could you provide me with the exact URL or a reliable way to verify the authenticity of the Uniswap website? Additionally, are there any specific security measures or recommendations I should follow when using Uniswap or any other cryptocurrency platforms? Thank you for your assistance in this matter.
