Alert fatigue

Too many alerts, a first look at each.

When there are more alerts than people, the important one gets lost among the routine ones. armor360 takes the first look at each alert and puts what needs a person at the top.

The noise hides the attack.

Alert fatigue is not a lack of effort. It is what happens when people are asked to give equal attention to far more alerts than they can.

  • Most alerts are routine

    Backups, admin scripts, software updates and scanners all trip rules. Each one still has to be checked before it can be closed, and the checking is the same tedious routine every time.

  • Attention wears thin

    After a long run of harmless alerts, the next one gets a quicker look. That is human, and it is exactly when a real attack slips past as one more thing to close.

  • Alerts arrive in pieces

    One attack can raise many alerts from different rules over hours or days. Looked at one by one, each seems minor, and nobody sees that they belong to the same story.

  • Rules make it worse

    A new rule that fires too often adds to the pile on day one. Without a way to test it first, teams find out a rule is noisy only after it has buried the queue.

From a pile to a priority list.

Each alert gets a first look and a verdict, so the people on shift start from what matters.

Alerts arrive in any order. Each gets a verdict, then the list reorders: real attacks on severe alerts first, harmless ones last, each with its reason.

A verdict on each alert, ready when a person looks

New alerts are collected automatically from your tools. The agent investigates each one and gives it a verdict: real attack, suspicious, harmless or not sure. Each comes with how sure the agent is and the reason, so a person reads a conclusion rather than starting from nothing.

Real attacks first

The queue is ordered by the agent’s verdict together with each alert’s severity, not by when alerts arrived. Real attacks and suspicious findings rise to the top; routine activity the agent judged harmless sits lower, with its reasoning there to check. A person can change the order, and the team spends its sharpest attention where it matters most.

The working, not just the answer

For each alert the agent asks questions and answers them from your data, keeping every record it uses. In our lab, a reconnaissance alert took 13 questions, 22 records and 4 data sources, and ended as a real attack at 90% confidence in 5 minutes 35 seconds.

  • What ran on the machine, and what started it
  • Who was signed in, and what else they did
  • Other alerts on the same host
  • What threat intelligence says about the addresses involved

Many alerts, one attack

Alerts that belong together are joined into an attack chain and a campaign, in the order they happened. Instead of twelve separate alerts from five rules, your team sees one attack, from discovery to collection, with the machines and accounts it touched.

Fewer noisy rules in the first place

Before a new detection rule goes live, armor360 shows how often it would have fired on your stored past alerts. A rule that would have buried the queue is caught before it reaches anyone, and a person approves each rule before it is switched on.

How the queue gets lighter.

  1. 1

    Alerts keep coming

    Your rules fire as they do today, noisy ones included. armor360 collects the new alerts from your tools automatically, without anyone copying them across.

  2. 2

    A first look at each

    The agent investigates each alert with the same checks each time, at any hour, and gives a verdict, a confidence and a reason backed by evidence.

  3. 3

    The noise sinks

    Priority comes from the verdict and the alert’s severity, so real attacks rise and harmless findings sit lower, still open to check. Related alerts join into campaigns.

  4. 4

    Attention goes where it counts

    People read the verdicts that need them first and correct any they disagree with. New rules are tested against past alerts, so fewer noisy ones are added.

What takes the weight off.

  • Automatic collection

    New alerts are pulled from your tools as they appear, without anyone copying them across.

  • Confidence shown

    Every verdict says how sure the agent is, so your team knows which to read closely.

  • Ordered by verdict

    Priority comes from the verdict and the alert’s severity, real attacks first, and a person can change it.

  • Corrections remembered

    When a person changes a verdict, that context is used in later investigations about your company.

  • Campaigns

    Related alerts joined into one attack, so the team works it once instead of piece by piece.

  • Rules tested first

    See how often a rule would have fired on past alerts before it goes live.

A long queue, by hand and with armor360.

TopicBy hand todayWith armor360
Routine alertsBackups, scanners and admin scripts each need the same checks before they can be closed, again and again. The agent runs those checks itself and marks known routine activity harmless or authorised, with the reason kept.
AttentionAfter a long run of harmless alerts, the next one gets a quicker look, whatever it turns out to be. The agent applies the same checks at the end of a long night as it does at the start of the day.
OrderAlerts are worked roughly in the order they arrived, so a real one can wait behind many routine ones. Real attacks and suspicious findings rise to the top, from the verdict and the severity, and a person can reorder them.
Related alertsPieces of one attack are closed one by one as minor, and nobody sees that they form a pattern. Alerts naming the same machine, account or address within about two hours are joined into one campaign.
New rulesA new rule that fires too often is found out only after it has already buried the queue. armor360 shows how often a rule would have fired on past alerts while it is still a draft.

Frequently asked questions

Does it just hide alerts it thinks are harmless?

No. Each alert stays in the queue with its verdict, how sure the agent is and the reasoning behind it. Harmless findings are placed lower so real attacks come first, but anyone can open one and check the evidence.

If a person disagrees, they change the verdict and add context. That correction is remembered, so the agent handles similar alerts about your company better next time.

What if the agent is wrong?

It will sometimes be, which is why a person reviews verdicts and why every one shows its evidence. The confidence figure tells your team which verdicts to read most carefully, and "unsure" is an honest answer the agent can give when the evidence is thin.

Corrections become part of what armor360 knows about your company, so the same mistake is less likely to be repeated.

Do we need to tune our rules first?

No. armor360 works from the alerts your rules already raise, noisy ones included. Over time it helps you tune: it shows how often a rule would fire on past alerts before it goes live, and when a person asks, the agent drafts a new rule, which goes live only once a person approves it. The rule library also shows which rules your data can feed today, so you can see where the gaps are.

What do our analysts still do?

They review verdicts, decide what to do and act. armor360 recommends next steps but does not change your machines or accounts. With the routine first look done, analysts have time for the work that needs a person: confirming real attacks, talking to the people affected, hunting for what rules missed and improving detection. Every verdict they correct also makes the next investigation better informed.
