This vendor risk report is based on UpGuard's continuous monitoring of Ryan's security posture using open-source, commercial, and proprietary threat intelligence feeds. The results are summarized into a security rating based on the analysis of hundreds of individual checks across five risk categories: website security, email security, phishing & malware, brand & reputation risk, and network security.
When secure cookies are not used, there is an increased risk of third parties intercepting information contained in these cookies. The website configuration should be changed so that all 'Set-Cookie' headers include 'secure'.
Browsers may display this website's content in frames. This can lead to clickjacking attacks.
No valid Content Security Policy is implemented. This increases the risk of XSS and clickjacking attacks.
Exposing a specific ASP.NET version in the ASP.NET version header makes it easier for attackers to exploit certain vulnerabilities. The website configuration should be changed to remove this header completely.
Exposing the ASP.NET version header indicates that the site is built with ASP.NET, which makes it easier for attackers to exploit certain vulnerabilities. The website configuration should be changed to remove this header.
Browsers may interpret files as a different MIME type than what is specified in the Content-Type HTTP header. This can lead to MIME confusion attacks.
Ensuring the server information header is not exposed reduces the ability of attackers to exploit certain vulnerabilities.
Information about specific technology used on the server is obscured.
Using HttpOnly cookies reduces the risk of client side script attacks, by preventing cookies being read on the client.
The website's Referrer Policy is not configured to allow unsafe information to be sent in the referrer header.
The page appears to be maintained.
DMARC reject policy provides the most effective protection against fraudulent emails being sent from a domain.
DMARC protects against fraudulent emails being sent from a domain.
Sender Policy Framework (SPF) record strictly enforces specific domains allowed to send email on its behalf.
Sender Policy Framework (SPF) record passes basic syntax checks.
DMARC policy percentage is set to default 100%, ensuring all mail is covered by the policy.
Sender Policy Framework (SPF) record does not include the ptr mechanism.
DNSSEC records prevent third parties from forging the records that guarantee a domain's identity. DNSSEC should be configured for this domain.
Domain is not protected from unsolicited deletion requests with the registrar or registry. The domain should have clientDeleteProhibited or serverDeleteProhibited set.
Domain is not protected from unsolicited update requests with the registrar or registry. The domain should have clientUpdateProhibited or serverUpdateProhibited set.
The domain does not contain a valid Certification Authority Authorization (CAA) record. A CAA record indicates which Certificate Authorities (CAs) are authorized to issue certificates for a domain.
No unregistered MX records that could lead to receiving mail on behalf of the target organization were detected.
Domain has not expired.
No dangling DNS records that could lead to subdomain takeover were detected.
Domain does not expire within 30 days.
Domain is not flagged as inactive.
Domain is not pending deletion with the registrar.
Domain is not pending restoration with the registrar.
Domain is protected from unsolicited transfer requests.
Domain is not under a DNS resolution hold with the registrar.
Domain is not under a DNS resolution hold with the registry itself.
Domain is not prohibited from renewal at the registry itself.
Without HSTS enforced, people browsing this site are more susceptible to man-in-the-middle attacks. The server should be configured to support HSTS.

SSL intermediate and root certificates do not expire within 20 days.
The SSL certificate presented by the server has an expiration period shorter than 398 days.
SSL certificate does not expire in less than 20% of its total valid period.
Industry standard SHA-256 encryption in use.
The site's public certificate provides at least 112 bits of security strength.

Jquery UI 1.12.1 has vulnerabilities which might be exploitable under certain conditions. Affected domains should be checked to determine which vulnerabilities might pose a risk.
HTTP.sys in Windows Server 2008 R2 SP1, Windows Server 2012 Gold and R2, allows remote attackers to execute arbitrary code via crafted HTTP requests.
A bug in OpenSSL's implementation of the TLS heartbeat extension allows access to portions of memory on the targeted host e.g. cryptographic keys and passwords.
The server does not support SSLv3, and is not vulnerable to the POODLE attack.
The server does not offer RSA_EXPORT cipher suites, so clients are not vulnerable to the FREAK attack.
The server is using strong Diffie-Hellman parameters and is not vulnerable to the Logjam attack.
