On watch over your cloud, including at 3 a.m.
We are a small team of senior platform and security engineers. We work with fintech and e-commerce companies in Latin America: we keep your infrastructure running, keep it secure and keep an eye on what it costs.
Every engineer has more than 10 years of experience. We work with AWS, Azure, GCP and Kubernetes, and we prefer open source tools so you pay for fewer licenses in dollars.
Twelve o’clock and all’s well!
How the night watchman called the hour.
- Mexico City
- Bogotá
- Lima
- Santiago
- Buenos Aires
- São Paulo
For centuries, in cities across Spain and Latin America, the sereno walked the streets at night with a lantern, calling out the hour and the sky: ¡Las doce y sereno!
Twelve o’clock and all’s calm. We work the same shift, on your infrastructure.
What we do
Start with a short audit or a specific compliance goal. If it works for you, we stay on as your platform team.
2-week infrastructure audit
We review cloud costs, security and Kubernetes. You get a report with estimated monthly savings in USD and risks ranked by priority.
Chile’s Laws 21.719 and 21.663
We turn Chile’s new data protection and cybersecurity requirements into concrete changes in your infrastructure.
SOC 2 and ISO 27001
To sell to US customers: we implement the technical controls and automated evidence your auditor asks for, without slowing your product team.
24/7 platform team
Operations, on-call, patching, cost control and threat detection, as a monthly subscription.
Why Sereno
We are small on purpose: everyone who touches your infrastructure has been doing this for more than 10 years.
- Senior people only
- No juniors learning on your account. You talk to the person doing the work.
- 24/7 without hiring five people
- Engineers in several time zones split the day and the night between them.
- Security from the start
- Controls in the pipeline, least privilege, properly stored secrets and evidence ready for the audit.
- The bill in plain sight
- Your cloud is paid in dollars. Every month we show you where the money goes and how to spend less.

Hiring your own team or working with Sereno
What we usually see when a company builds the team in-house.
| In-house team | Sereno | |
|---|---|---|
| Time to start | 2 to 4 months of hiring | 1 to 2 weeks |
| 24/7 coverage | Needs 4 or 5 people on call | Included in the Scale plan |
| Knowledge | Whatever one or two people know | Platform, security, databases and development |
| Turnover | When someone leaves, their knowledge leaves too | Everything is documented and kept as code in your repository |
| Cost | Salaries, payroll taxes and recruiting | Fixed monthly subscription in USD |
Questions
What language do you work in?
Technical work and meetings are in English. Reports and documentation can also be delivered in Spanish.
How do you bill?
Monthly, in USD, in advance. Contracts are signed with our EU-based company.
Do you have references?
Our work is under NDA, so we don’t publish client names. On the call we show demos and go into the technical detail of what we’ve built.
How do you access our systems?
Read-only access first, with MFA and least privilege. Everything stays in your cloud accounts and repositories, and we sign an NDA before any access.
Do you work with our existing team?
Yes. We can be your whole platform team or join your engineers for on-call, security or specific projects.
