Vulnerability monitoring

We learn about exploited vulnerabilities before you have to

Of the tens of thousands of vulnerabilities published each year, only a small share is ever attacked. We watch exactly those, and when one affects your site or server we tell you in plain words: what it threatens, what to do and by when. And if there is no one to fix it, we fix it ourselves at a fixed price. Before customer data leaks, not after the fine.

0-day pipeline

How it works

  1. 01

    Feeds come to us, not to a cloud

    CISA KEV, the NVD window, the Exploit-DB export and a GitHub PoC search sync into local storage. Customer data never goes to third-party services.

  2. 02

    Matched to your stack

    From Server / X-Powered-By banners and the declared stack of each stand we pick only the CVEs that concern your infrastructure, not “every CVE”. Fresh KEV entries and the ransomware flag are marked separately.

  3. 03

    Alert and actions

    A new KEV entry with a BOD 22-01 due date or a fresh PoC on GitHub, and you get a digest: what happened, what is at risk, what to do. With CVSS, EPSS and links to PoCs and advisories.

  4. 04

    We fix it ourselves

    No need to look for a contractor: the team that found the vulnerability fixes it at a fixed price and re-checks that the hole is closed.

What you get

Two formats

Start with a free check of one domain. If your stack is live and changing, add monitoring.

Express check

free

One domain you have confirmed

  • Safe checks with no payloads: banners, TLS, HSTS, CSP, cookies, version disclosure, .git and .env signatures
  • Your infrastructure matched against KEV, NVD, Exploit-DB and the PoC archive
  • Prioritised list of candidate CVEs: CVSS, EPSS, ransomware flag
  • In plain words: what to close right now and what delay would cost
  • An estimate for the fix: we can close what we found ourselves

Found it, fixed it

Most services send a report and leave you alone with a list of vulnerabilities. We are the same team that fixes what we find.

  • Fixed priceAn estimate before work starts, no hourly billing.
  • No hand-offsWhoever found it fixes it: no context is lost.
  • Re-checkAfter the fix we verify the hole is closed.

In money

What a missed vulnerability costs

A breached site with a customer database is a personal data leak. Fines for a company under Russian law:

₽3–15M
first leak

Depends on the number of people affected, Art. 13.11(12–14) of the Administrative Code.

up to ₽3M
staying silent

For not notifying the regulator of a leak within 24 hours.

1–3% of revenue
repeat leak

At least ₽20M if a leak happens again within a year.

A year of subscription starts at ₽360,000, eight times less than the minimum fine for one leak. Site downtime and ransomware recovery are not included in that.

How we differ from a typical vendor

  • Exploited CVEs, not 25,000 a year

    We cut the noise with KEV, NVD, EPSS and ransomware flags. The report shows what is being attacked now.

  • Findings with reasoning

    We mark where a manual check is needed. No “everything is bad” without evidence.

  • The legal frame is built in

    We only check stands you have authorised. The list lives in a verified configuration; someone else's domain cannot get there.

  • Data does not fly off to clouds

    Feeds are kept in a local mirror and correlation runs on our side. Reports are not sent to third-party services.

    The PHP your site runs on has a flaw that is already being used in attacks

    CVE-2026-109618 · stand shop-prod

    The risk
    An attacker may take over the server and with it the customer and order database. That is a personal data leak: a fine from ₽3M. Write-ups of the flaw are already public, so attackers see them too.
    What to do
    Update PHP on the server to a fixed version. If that cannot happen at once, apply the vendor's interim mitigation.

    We can fix it. We update PHP ourselves in an agreed window and check the site works and both flaws are closed. Fixed price agreed before we start.

    The risk
    The same attack chain as above. Public tools check for both flaws at once.
    What to do
    Nothing beyond the update above. Afterwards we confirm both flaws are closed.

    We can fix it. Part of the same update, no extra charge.

    An old PHP vulnerability used by ransomware gangs

    CVE-2024-4577 · stand shop-prod

    The risk
    Gangs that encrypt data and demand a ransom use it. The result is site downtime and restoring from backups.
    What to do
    Check the PHP version and how it is run. The match is by product name: if the version is already patched, there is no risk.

    We can fix it. We check the version ourselves. If it is vulnerable, we close it with the update above.

    A well-known nginx + PHP-FPM vulnerability, also used by ransomware gangs

    CVE-2019-11043 · stand shop-prod

    The risk
    With a certain nginx configuration it lets an attacker run code on the server.
    What to do
    Update PHP-FPM and review the nginx configuration. As above, we check the version first.

    We can fix it. We review and, if needed, fix the nginx configuration ourselves.

Boundaries

  • The digest lists candidates and priorities, not proof.
  • Matching is by product name; versions may differ - check the advisory.
  • No exploitation is run: the digest sends no attack requests to the stand.
