Office 365 High Severity Alert
"If “high severity” means “figure it out yourself,” something’s wrong. When a "Mass file download" alert hits, your team bounces between admin portals, guessing if it is a breach or a contractor in a cafe. 1Security adds the forensic context missing from native tools. Stop guessing and respond in minutes, not days.
What is the challenge?
Doing It with 1Security
High-pressure moments expose weak tooling fast. Alerts should shorten response time, not stretch investigations. Without context, Office 365 alerts leave teams guessing, hesitating, or escalating too late. 1Security adds the missing context so alerts turn into decisions, not distractions.
Context-rich alerts
Every alert includes context on the affected resource, sensitive data exposure, and related permissions, so teams can judge impact quickly without digging through raw logs.
Less noise, more signal
1Security consolidates activity, permissions, and sensitivity signals into single source of truth, helping teams focus on meaningful risky access changes instead of chasing fragmented, low-context alerts.
Unified risk view
1Security replaces switching across admin centers by consolidating inventory, permissions, sensitivity, and activity signals in one place, so investigations start with context, not guesswork.
Faster investigations
Alerts include context on resources, exposure, and permissions, helping teams trace what changed and investigate incidents faster than manual log analysis or repeated CSV exports.
Remediation workflows
1Security pairs alerts with workflows and remediation options, such as addressing risky external sharing and privilege escalations, so teams can respond consistently and document actions taken.
Incident timelines
Each alert is recorded with a clear, chronological timeline showing detection, investigation, and response actions, making post-incident reviews and audits straightforward.
Solving It with Other Methods
Most teams try to manage high severity alerts with native Microsoft tools and manual workarounds. It technically works, but only if you enjoy switching portals, waiting for logs, and hoping nothing important happens meanwhile.
