Security Ready | Vulnerability scanning for your company's website and servers
We scan from the outside, and also look inside your servers and PCs (Windows and Linux). Using open-source scanning tools trusted worldwide, we check regularly and send you only the problems that apply to your servers, together with what to do about them, in plain language.
Matched against a worldwide set of checks(release of Oct 23)

Is this enough?
Here is where attacks actually come in, according to Japanese government research, next to what Security Ready checks every week.
Japan's National Police Agency: how ransomware got in (first half of 2025, 45 cases)
Over 80% came in through weak spots in entry points visible from the internet (VPN devices and remote desktop). Security Ready checks every week for open entry points and known vulnerabilities in the software running on them, and on the day a critical vulnerability is published, it checks that same day.
IPA (Japan's Information-technology Promotion Agency): main weak spots found when scanning 126 small businesses from the outside
| Weak spot found | Security Ready |
|---|---|
| Unencrypted connections (HTTP, FTP) | β |
| Expired or self-signed certificates | β |
| Databases visible from the outside | β |
| Git contents or settings files visible | β |
| Known vulnerabilities (OpenSSH, etc.) | β |
| Missing security headers | β |
| Problems with SPF or DMARC | β |
| Cookies without security flags | β |
| VPN or admin login pages visible | β |
| DNS zone transfer misconfiguration | β³ Coming |
β³ means we are still building this out. What we can't do is listed honestly under "What we can and can't do".
The same tools the experts use
nmap, nuclei, OWASP ZAP and testssl.sh: open-source tools used by security professionals worldwide, with new checks added every time a new weak spot is published.
14,104 checks
Published vulnerabilities, files that should never be visible, old encryption, doors left open, and fake-email settings, all checked together.
Honest about the gaps
Deep testing of screens behind a login, and loopholes in business processes, need a human tester. Combining us with a human test once a year gives you peace of mind.
Sources (in Japanese): National Police Agency, "Cyberspace threats in the first half of 2025" (as published by Nagasaki Prefectural Police) / IPA, summary of the report on ASM assessments and case studies (published March 2026)
You have a website and servers, but no one checks whether they are safe. You don't know where to start.
A test by a security firm typically costs thousands to tens of thousands of US dollars each time. Any new vulnerabilities published in between go unnoticed.
Even when you get the report, you can't tell which problems are really dangerous or what you are supposed to do.
Security Ready fills the gap between tests by being affordable, frequent and easy to understand.
Vulnerability scanning today
01
The number of published vulnerabilities grows every year, with about 100 new ones found every day. It's no longer realistic for a person to check them all each time.
With Security Ready: Twice a day (6:00 and 18:00 JST), we automatically pull new vulnerabilities from public databases and compare them with how your servers are set up.
02
It's not unusual for attacks to start within days of a vulnerability being published. A once-a-year test won't catch vulnerabilities that appear in between.
With Security Ready: Each time new checks come out, we scan for just those. Because the load on your server is small, we can do this often.
03
ASM (attack surface management), which keeps watch over the entry points attackers can see from outside, is spreading. Japan's Ministry of Economy, Trade and Industry (METI) published an introduction guide for it in 2023.
With Security Ready: We automatically find subdomains and spot changes in your open ports and software, so we also watch entry points that appeared without you noticing.
04
In "10 Major Security Threats", the annual list by IPA (Japan's Information-technology Promotion Agency), attacks that go through business partners and contractors rank near the top. Small businesses and group companies often become the weak link.
With Security Ready: You can manage each company separately, and a head office can see the number of unfixed problems across the group in one list. Even companies with no security person get clear to-dos in plain language.

Features
Just enter your domain. We score the weak spots anyone can see from the outside, show you how an attacker would most likely come in, and tell you what to fix today. No sign-up needed.
Install our plugin and we check every day whether WordPress itself, your plugins, your themes and PHP are out of date. We also flag risky plugins that are no longer maintained. Works on shared hosting too.
Create a PDF of your security measures that follows the 26 items of β 3 in SCS, the supply-chain security evaluation scheme being set up by Japan's Ministry of Economy, Trade and Industry (METI) and IPA. Anything our scans can tell (outdated software, unfixed vulnerabilities, exposed entry points) is filled in for you.
For each finding we show how to fix it on your setup. Once you've fixed it, press "I fixed it, check again". We re-scan just that problem and keep a record that it's fixed.
Every morning we search public certificate records for forgotten subdomains, such as old campaign sites or test servers. If one points to something that no longer exists and could be taken over, we tell you right away.
We turn the weight of your unfixed problems into a score out of 100, and show how you rank within your industry and overall. (We never show anyone other companies' names or scores.)
Besides scanning from the internet, a read-only inspection program looks inside your servers and PCs (Windows and Linux). It checks for outdated software, whether the firewall and antivirus are on, your password rules, and even backdoors planted on your site (signs of a break-in).
We don't list every vulnerability in the world. We only show problems that match how your servers are set up, most serious first.
Each finding comes with a short note on how to fix it. Severity has four levels: Critical, High, Medium and Low.
We only run checks for newly published vulnerabilities and look at what changed since last time. This puts very little load on your server, so we can scan often.
Protection against fake emails in your name, encrypted connections (HTTPS), basic website settings, your server's open doors (ports), and known published weak spots (vulnerabilities). We use the standard scanning tools that security professionals use.
Keep each server's setup (operating system, web server, database and their versions), scan history, permission records and the person in charge together in one place.
Get a PDF report per server or per company in one click. Use it as-is to brief your team or report to your clients.
How it works
Choose whether you are the site's administrator or an agent with the administrator's permission (such as a web agency), and tick the box to accept responsibility. No DNS changes needed.
Record what may be checked, for how long, at what times, and the maximum number of requests per second. Anything outside that is stopped automatically.
We load the latest checks before every scan. If something changed since last time, more detailed checks are added automatically.
Your screen shows only the problems that affect your servers, each with what to do. You can download the report as a PDF.
Emergency response
No need to wait for the next scheduled scan. We pull in new vulnerabilities twice a day (6:00 and 18:00 JST), pick out only the ones that match your servers' setup (operating system, software and versions), and alert you right away.
Published
A critical vulnerability is added to a public database.
6:00 and 18:00 JST
Twice a day we pull in new vulnerabilities and check whether they affect the operating systems, software and versions on record for your servers.
As soon as it matches
We tell you in plain language which server is at risk, what the problem is, and how to fix it.
During your allowed hours
If you turn on automatic scans, we check from the outside whether your server is really affected.
A typical scheduled scan
Runs the same checks at the same time, and that's it. You can't see when a new vulnerability was added to the checks.
Security Ready
Shows on screen when new vulnerabilities were last pulled in. When one that affects you appears, we check for that vulnerability specifically and send you the result and what to do.
Updated daily
Pulled automatically from a public database twice a day (6:00 and 18:00 JST) and compared with the setup of registered servers.

What we check
"Outside view only" puts almost no load on your server. "Standard" checks run only during the hours agreed with you.
| Area | What you learn | How we check |
|---|---|---|
| Protection against fake emails | Whether you have the settings that stop fake emails sent in your company's name (SPF and DMARC), and whether your address book (DNS) has been changed without your knowledge | Outside view only |
| Encrypted connections (HTTPS) | Whether the ID card behind the padlock (your certificate) has expired, or whether old, easy-to-break encryption methods are still enabled | Outside view only |
| Basic website settings | Which software and versions you run, the settings that tell browsers how to handle your site safely, and how login information is stored in the browser | Outside view only |
| Your server's open doors (ports) | Whether doors that should never face the internet, such as your database or admin access, are open | Standard |
| Published weak spots (vulnerabilities) and misconfigurations | Whether vulnerabilities published worldwide affect you, and whether files or admin pages that should be hidden are visible | Standard |
| Internal scan (inside your servers and PCs) | The versions of all software installed on Windows and Linux, whether Windows Update has stopped, whether unsupported Windows or Office is still in use, and whether remote-control software is installed (using a read-only inspection program) | Runs inside |
We use standard open-source scanning tools (their code is public) that security professionals around the world rely on: nmap, nuclei, testssl.sh, httpx and more.
When we find a weak spot
Findings are listed most serious first, each with what to do.
Critical and High findings are sent instantly to Slack, Teams or Discord.
The "what to do" text can be forwarded as-is to your web agency or hosting company. If you have a reason not to fix something, you can write it down and mark it "No action needed".
If a problem is gone at the next scan or the twice-daily check, it moves to "Fixed" and is noted in the report. Serious problems left unfixed get a reminder every 7 days.
Security Ready never changes anything on your servers.
Reports
The sample is a real scan of our own test server, which we deliberately left with weak spots. Only the company name, server names and addresses have been replaced with made-up ones. Reports are currently produced in Japanese.

See all 18 pages (PDF, Japanese)Safety
Done carelessly, vulnerability scanning looks just like an attack. Checking permission is at the core of how Security Ready works.
We only scan servers where someone has declared they are the administrator or a legitimate agent, and the permission is on record. We record who declared it, when, and from where, and we check the allowed scope twice: when the scan is requested and right before it runs.
We don't run load tests, try passwords by brute force, or try default passwords.
We stay within the requests-per-second limit set in your permission, and we don't run outside the agreed hours.
We don't use testing tools that rely on outside callback servers (such as interactsh), and only the account holder can see the results.
If anyone raises a concern, one button stops all scans.
If a name points to an internal office or home network address, we don't scan it.
Even without a security person, you'll know what to fix.
Keep each client separate, and hand the reports straight to your clients.
See the number of unfixed problems across the group in one list, while each company's staff see only their own.
What we can and can't do
Most attacks on servers start with "holes visible from the outside": outdated software, settings files published by mistake, databases left open to the internet, and certificates about to expire. Security Ready specializes in watching for these holes, again every time a new vulnerability is published. On the other hand, it can't find the kinds of weak spots that take human thinking to uncover. We tell you honestly what we can't do, too.
Software with published vulnerabilities
We judge this from the versions of your web server, programming language, database, CMS and so on. If a version can't be seen from outside, enter your setup and we'll still check it.
Files and pages that should never be public
Settings files (such as .env), source control data (.git), and exposed admin or debug pages.
Dangerous doors open to the internet
Whether things like your database or remote server access can be reached from the outside.
Problems with encryption and certificates
Expired or soon-to-expire certificates (the ID card behind the padlock), and old encryption methods.
Protection against fake emails
Whether SPF and DMARC are set up correctly.
Changes you didn't notice
Newly opened doors (ports), software that was swapped out, and forgotten branches of your web address (subdomains).
Flaws specific to your business processes
Loopholes in the rules of that particular system, like "I can see other customers' orders" or "skipping a step lets discounts stack".
Access-right loopholes
For example, a regular member being able to use admin features. A person has to compare what each logged-in user can see.
Full attack testing through input forms
Tests that go through each screen and try attacks such as sending malicious commands through a form (SQL injection). Security Ready only runs standard, pattern-based checks.
The inside of your network, and your source code
Our internal scan checks settings and outdated software inside each server, but your whole office network and reading the program code itself (source code review) are not covered.
Protection against attacks that trick people
Such as training staff on targeted phishing emails, or reviewing your internal rules.
| If your site or server is⦠| We recommend |
|---|---|
| A site with no login, such as a company profile, recruiting page or blog | Security Ready alone is enough in most cases |
| A site with a contact form or a brochure request form | Security Ready is often enough. If your forms are custom-built, have a human test them at least once |
| Member logins, an online shop or a booking system | Combine a human test (about once a year) with Security Ready in between |
| Business systems for outside users that handle lots of personal data or money | Human testing is essential. Use Security Ready for day-to-day monitoring |
Finding nothing is not a guarantee that there are no vulnerabilities. Every report states how we scanned and what the scan can't cover.

In human testing (a penetration test), experts log in and go through the system screen by screen, looking for loopholes unique to that system, such as "I can see other customers' orders" or "a regular member can use admin features". It typically costs thousands to tens of thousands of US dollars and is done about once a year. Security Ready is automated, so it can't find loopholes like these. Instead, it keeps watch every day, at low cost, for published weak spots, outdated software, misconfigurations and exposed entry points, and tells you within half a day when a new vulnerability affects you. For a company information site, Security Ready alone is usually enough. If you have member logins or an online shop, we recommend combining it with a human test once a year.
Testing done by hand by a security firm's experts typically costs thousands to tens of thousands of US dollars each time. Automated scanning tools often cost hundreds of dollars per month. Because Security Ready focuses on automated scanning from the outside, your first scan is free, and ongoing plans start at USD 19 per server per month.
Yes. Your first in-depth scan is free (one server per company). You can decide whether to continue after seeing the results and the report.
Yes. When we find that a site runs WordPress, we compare the WordPress version with published vulnerabilities and also run checks for known vulnerabilities in plugins and themes. Outdated WordPress and plugins are a common way in for site takeovers and defacement.
A simple method that the Japanese police also recommend: search Google for "site:yourdomain" and look for pages you don't recognize. Security Ready does not monitor for defacement itself. Instead, it checks every day from the outside for the weak spots that lead to takeovers and defacement (outdated software, open entry points, files that should be hidden, and so on) and tells you how to close them.
Yes. We check from the outside whether the settings that stop fake emails in your name (SPF and DMARC) are in place and not too weak. If something is missing, we show you example settings.
More and more companies are being asked by their business partners to explain their security measures, for example under the "Security Measures Evaluation Scheme for Strengthening Supply Chains" (SCS) that Japan's Ministry of Economy, Trade and Industry (METI) and IPA are preparing. Security Ready is not a certification or an official evaluation, but it can create a PDF "document for business partners" that summarizes your measures along the 26 items of β 3 in the scheme. Items our scans can tell, such as outdated software, unfixed vulnerabilities and exposed entry points, are filled in automatically; things like internal rules you fill in as a self-assessment. (More details on our Japanese page about the scheme.)
It helps close the way in. According to Japan's National Police Agency, most ransomware attacks get in through VPN devices or remote desktop that are exposed to the internet. Security Ready finds these exposed entry points and the vulnerabilities that affect them, and alerts you. It does not replace backups or your in-house security measures.
No. Before scanning, you must declare that you are the administrator or an agent with the administrator's permission, and agree that you are responsible for any damage caused by an unauthorized scan. A record of the declaration (who, when and from where) is kept. Government and local-authority domains are not scanned on the basis of a sign-up alone.
We're sorry for the trouble. Please tell us the domain name and the date and time using the contact form at the bottom of this page. We will check and stop the scans immediately. If someone made a false declaration, we will hold that person responsible under our Terms of Service.
A little, but we keep it small. Day to day we run light scans that look only at what changed, and we cap the number of requests per second. Heavier checks run only during the agreed hours.
Not necessarily. We use automated tools to check what is visible from the internet, so screens behind a login and flaws specific to how your business processes work are not covered. For important systems, we recommend also having experts test them.
No. We check from the outside. No DNS changes are needed either.
On each server's page, you can enter your operating system, database, libraries and their versions. We use what you enter to find vulnerabilities that apply to you.
You can view them on screen or download them as A4 PDFs. They include an overall grade (A to E), the list of findings, what to do, and how we scanned and what the scan can't cover.
You can also request your free in-depth scan here. Tell us roughly how many servers you have, and we'll show you how to get started.
For terms of use, please see our Terms of Service.
