Often different organizations have the same questions around our Dynamic Services offering so we’ve grouped them all together to address some key concerns...

How does Dynamic Services adapt to load? Does it auto-scale?

Dynamic services clusters, including Dynamic SPF, DKIM, DMARC, BIMI and MTA-STS are maintained in Google Cloud Platform (GCP) and separated from our main infrastructure which is hosted in IBM Cloud and/or Microsoft Azure. We have auto-scaling redundant clusters serving SPF, DKIM and DMARC with separate clusters for SPF and DKIM/DMARC/MTA-STS so in the unlikely event that one were to fail, DMARC would still pass

How is Dynamic Services protected against DoS (Denial of Service) attacks?

Red Sift follows the best practice recommended by GCP to protect and mitigate against DoS and DDoS attacks.

How does Red Sift minimize the impact of any Dynamic Services outages?

We have built failover and geo-redundancy into the system to ensure the likelihood of all our clusters being down at the same time is extremely low.

What failover systems are in place in the unlikely event of a Dynamic DMARC outage?

We have a 24/7 on-call engineer rotation in place to address any unlikely outages. To receive a report of our SLA please contact us here.

To give you an example, we have a large Telco relying on our Dynamic SPF service to process millions of SPF requests for them daily. They have telco grade infrastructure across the world that authenticates via this service and our approach continues to provide an optimal solution even at this scale.
