SparkPost Security Program

Our customers ask us about SparkPost’s security posture on a routine basis. As a general rule we don’t want to expose detailed information about our security program because we don’t want to provide intelligence to bad actors. However, we realize information security is imperative and our customers need to know that we are employing a security program to protect their information. To this end, we have outlined at a high level the measures we take to protect our customer’s data.


SparkPost is SSAE-16 SOC II Type 2 Certified. We have certified both our cloud and corporate environments. In our effort to constantly improve our security posture, we are now turning our attention to ISO 27001 and beginning the process to secure this next level of assessment and certification.
