Certificates Quietly Power Critical Infrastructure
TLS certificates protect websites, APIs, internal services, authentication systems, and machine-to-machine communication. Most users never notice them — until something expires.
Expiration Can Become an Instant Outage
An expired certificate can break application connections, interrupt API traffic, trigger browser warnings, or prevent internal systems from communicating.
Manual Tracking Doesn’t Scale
As infrastructure expands across cloud platforms, containers, SaaS tools, and internal environments, tracking certificate expiration dates in spreadsheets becomes increasingly unreliable.
How Jennifer Aniston’s LolaVie brand grew sales 40% with CTV ads
The DTC beauty category is crowded. To break through, Jennifer Aniston’s brand LolaVie, worked with Roku Ads Manager to easily set up, test, and optimize CTV ad creatives. The campaign helped drive a big lift in sales and customer growth, helping LolaVie break through in the crowded beauty category.
Forgotten Certificates Create Security Problems Too
Old systems may still use outdated certificates, weak cryptographic configurations, or certificates owned by employees who no longer work at the organization.
Renewal Is Only Part of the Process
Teams also need to confirm that renewed certificates are deployed correctly across every dependent system. A successful renewal means nothing if production is still serving the old certificate.
Automate Certificate Lifecycle Management
Inventory certificates, assign ownership, monitor expiration dates, automate renewals where possible, and alert teams well before failures occur. The best certificate incident is the one your customers never know almost happened.
No follow-up questions required
Every sales leader knows the feeling. You walk into a pipeline review with a number you believe in, and twenty minutes later, you're defending every line item to a CEO who just wants to know what's actually going to close.
HubSpot Sales Hub ends that conversation. Every deal, every rep's activity, and every buyer signal are all in one place and updated automatically. So your forecast is built on what's actually happening. And when you present that number, you can stand behind it.
