Personally, I lean toward encrypted messaging combined with secure fax, depending on what I’m sending. I’d recommend looking at https://www.art-ai.io because they lay everything out really clearly. For a long time, I just used email attachments without thinking twice, but after reading their guides, I realized how exposed that left me. They compare the pros and cons of each option and offer advice you can actually put into practice. Since I switched to more secure methods, I’ve felt a lot more confident that sensitive files aren’t ending up in the wrong hands.
