Is it safe to keep money in Uphold?

Could you please elaborate on the safety aspect of storing money in Uphold? I'm considering using their services but I'm concerned about the security measures they have in place. Do they employ robust encryption techniques to protect user funds? Are their servers and databases regularly audited for vulnerabilities? Also, what kind of insurance or compensation policy do they offer in case of any security breaches or losses? I'd like to know how reliable and trustworthy Uphold is in terms of safeguarding customers' financial assets. Thank you for your insights.
