Keeping DLP usable as Chrome changes
I built release monitoring, proposed a supported-site scanning design, and improved diagnostic guidance. Each addressed a different source of recurring work.
Catch compatibility failures early
Chrome major and minor updates sometimes broke DLP upload blocking. The team initially discovered these failures through customer cases and then rushed hotfixes.
I wrote a Python program to check Google's official API for new Chrome Beta and Stable versions. It fed a workflow that updated the browser, tested sensitive-file uploads, and emailed the team if blocking failed.
- New Chrome version
- Browser update
- Upload-blocking test
- Email on failure
This helped the team address compatibility issues before customer reports and reduced manual effort around Chrome releases.
Reduce resource use with explicit scope
Customers also reported slower browsing. During a team-led DLP refactor, I proposed limiting default browser scanning to a supported-site list. The team adopted and implemented the design.
Before
Scan website data by default
After
Scan supported sites
These relative reductions came from switching the site-list design alone, based on my recollection of the QA performance report. The original report is unavailable; the figures do not represent the whole refactor.
Improve the information in escalated cases
As SEG Leader, I returned incomplete cases with specific collection requests and assigned complete cases by priority, complexity, and workload. I initiated an illustrated DLP guide that taught L2 how to classify issues and collect the required diagnostics.
20-percentage-point drop in missing-data returns to L2
First month after the DLP guide rollout, according to figures shared by my manager. This is a case-return percentage, not resolution time or a relative 20% reduction.
Evidence and limits
- These cases describe my own work. I no longer have access to the original reports or internal records for independent verification.
- These resource savings came with a narrower default scanning scope. It does not prove unchanged coverage across all sites or the same improvement in page-load speed. Baseline values and workload details are not available.
- I wrote the Python monitor and proposed the site-list design, which the team implemented. Time saved through monitoring was not measured. The guide's 20-percentage-point result is separate from the performance tests.
