If your website doesn’t have a valid SSL/TLS certificate, browsers like Chrome and Firefox will show visitors a “Not Secure” warning. That warning sends most people away — and they don’t come back.

This article explains what SSL/TLS certificates are, why they matter to your business, and what happens when they expire.

What Is an SSL/TLS Certificate?

An SSL/TLS certificate is a small file installed on your web server. It does two things: it encrypts the data traveling between your website and your visitors, and it proves your website is legitimate.

When a certificate is in place, your website address shows “https://” instead of “http://”, and visitors see a padlock icon in their browser. That padlock tells them it’s safe to share information with your site — like a contact form, login credentials, or payment details.

You’ve probably heard both “SSL” and “TLS” used to describe these certificates. SSL (Secure Sockets Layer) is the older term. TLS (Transport Layer Security) is the updated version that replaced it in 2015. Most people still say “SSL” out of habit, but when you buy one today, you’re getting a TLS certificate.

Why Your Seattle Business Needs One

If your business has a website — and nearly every Seattle-area business does — you need an SSL/TLS certificate. Here’s why it matters beyond just the padlock icon.

Customer trust. When a visitor sees “Not Secure” in their browser, most will leave immediately. They assume your site isn’t safe, and they’ll find a competitor who looks more professional.

Google search rankings. Google uses HTTPS as a ranking factor. A site without a valid certificate can rank lower in search results, which means fewer people find you in the first place.

Data protection. Without encryption, data sent through your website — including contact forms and logins — can be intercepted by attackers. This is called a man-in-the-middle (MITM) attack. An SSL/TLS certificate stops that by encrypting the data in transit so no one else can read it.

Compliance. If your business handles sensitive customer data, regulations like HIPAA or PCI DSS may require encrypted connections. An expired or missing certificate can put you out of compliance.

Types of SSL/TLS Certificates

Not all certificates are the same. There are three main types:

Domain Validation (DV): The most basic option. It confirms you own the domain but doesn’t verify your business identity. Fine for simple informational websites.

Organization Validation (OV): Verifies both your domain and your business. Recommended for most small and mid-size businesses. It gives visitors more confidence that they’re dealing with a real, verified company.

Extended Validation (EV): The highest level of trust. Requires the most thorough verification process. Used primarily by banks, e-commerce sites, and healthcare organizations that handle large volumes of sensitive transactions.

For most small businesses in the Seattle and Tacoma area, an OV certificate hits the right balance of trust and cost.

What Happens When Your SSL Certificate Expires

This is where a lot of businesses get caught off guard.

SSL/TLS certificates don’t last forever. As of early 2026, certificates are valid for about 200 days. That number is shrinking — by 2029, the industry is moving toward 47-day certificate lifespans. That means more frequent renewals and more chances to let one slip through the cracks.

When a certificate expires, the consequences are immediate:

  • Browsers display a red warning page telling visitors your site is not secure
  • Visitors leave and are unlikely to return
  • Google may penalize your search rankings
  • Any data sent through your site is no longer encrypted
  • If you accept payments or collect patient data, you may fall out of compliance

Certificate expiration is one of the most common — and most preventable — causes of website downtime. Companies as large as Epic Games and Microsoft Teams have had outages because of an expired certificate that nobody caught in time.

Staying on top of renewals takes attention. Most businesses either set calendar reminders or work with an IT provider who monitors expiration dates proactively.

How to Get and Manage an SSL Certificate

If you’re using a website host like GoDaddy, Bluehost, or similar, they usually offer SSL certificates as part of your hosting plan. Free certificates are also available through services like Let’s Encrypt for basic domain validation needs.

For businesses that need organization or extended validation, or that manage multiple domains, the process is more involved. You’ll typically work with a certificate authority, go through a validation process, install the certificate on your server, and set a renewal schedule.

If managing that sounds like more than you want to handle, that’s a reasonable position to take. Many Tacoma and Seattle businesses outsource certificate management to their IT provider so they never have to worry about a lapsed certificate causing downtime or customer loss.

Don’t Let an Expired Certificate Hurt Your Business

An SSL/TLS certificate is one of the most basic pieces of your website’s security. It’s not expensive and it’s not complicated — but it does require ongoing attention, especially as renewal windows get shorter.
