Overview
CISA's Known Exploited Vulnerabilities catalog is a practical guide to what to patch first, even for private companies that aren't bound by it. We plan maintenance windows around your US business hours and time zones, patch operating systems and third-party software, and keep an auditable record of exceptions for SOC 2, PCI DSS and HIPAA reviews.
Many breaches exploit vulnerabilities for which a patch has been available for weeks or months. Patching sounds simple, but at scale it requires inventory, prioritization, testing, maintenance windows, rollback plans and proof that it happened.
Our managed patch service handles that end to end. We prioritize patches by exploitability and exposure — with known-exploited vulnerabilities fast-tracked — test them against representative systems, deploy in agreed windows and report compliance across your estate.
Patch status feeds into our vulnerability management program, so you can see risk actually going down.
How our managed services work for US organizations
- Round-the-clock cover through US nights, weekends and holidays, when in-house teams are offline
- Escalations to your named contacts by phone, email, Slack or Microsoft Teams, following agreed severities
- Monthly service reviews scheduled around your US time zone, with evidence packs for SOC 2, HIPAA and PCI DSS
- Delivered remotely from India, with data-handling terms agreed in the contract before onboarding

Frequently asked questions
Will patching cause downtime?
We use maintenance windows, staged rollouts and rollback plans to minimize impact, and test patches before broad deployment.
How fast are critical patches applied?
SLAs are agreed per severity. Actively exploited vulnerabilities on internet-facing systems are prioritized for emergency handling.
Do you patch network devices?
Yes, where in scope and supported by your maintenance contracts.
Can you support US organizations from India?
Yes. All services are delivered remotely by our team in India. India is 9.5 hours ahead of US Eastern time during US daylight saving time (10.5 hours in winter) and 12.5 to 13.5 hours ahead of Pacific time. Meetings and testing windows are agreed around your US time zone at scoping, and 24/7 services run around the clock.
Where is our data processed?
Engagement data is handled by our team in India under NDA, with encrypted storage, least-privilege access and secure deletion at the end of the agreed retention period. Data-handling terms are agreed in the contract. If you need something specific, such as US-only data residency or a business associate agreement, raise it at scoping and we'll tell you plainly whether we can meet it.
