Brand protection for startups comes down to six things, done in this order: clear and file your trademark, secure your domains, claim your social handles, make sure the company actually owns its brand assets, lock down your email domain, and watch for lookalike domains once people start trusting your name. The first four cost a few hundred to a couple of thousand dollars and are hardest to fix later. The last two are cheap and stop the attacks that hit startups most often.
Most startup advice stops at the trademark. That covers who can legally use your name. It does nothing about a phishing site on a lookalike domain that emails your customers an invoice tomorrow. This checklist covers both, by stage, so you spend money when it starts to matter.
Before you launch: lock down the name
1. Clear the name, then file a trademark
Search before you fall in love with a name. Check the trademark register in each market you plan to sell in, the domain, and the obvious social handles. A conflict found now costs an afternoon. A conflict found after launch costs a rebrand.
Then file. For most software startups the relevant classes are class 42 (software as a service) and class 9 (downloadable software). Official filing fees at the time of writing (October 2026), before any attorney fees:
- United States (USPTO): $350 per class for a base application, with surcharges if the description of goods and services is incomplete or free-form.
- United Kingdom (UKIPO): about £205 for one class filed online, plus about £60 for each extra class, after the April 2026 fee rise.
- European Union (EUIPO): €850 for one class, €50 for the second and €150 for each class after that. One filing covers every EU member state.
Fees change, so check each office's current fee schedule before you file. A trademark attorney usually adds $500 to $2,000 per filing, and is worth it if your name is close to an existing mark.
2. Secure your domains
Register the .com even if you launch on another TLD, plus the country domain of your home market. Then add the handful of variants an attacker would register first: the most common one-letter typo, the hyphenated version, and your name plus the words your customers type next to it, such as "login", "app" or "pay". You do not need hundreds. Five to fifteen well-chosen names cost less than a hundred dollars a year and close the cheapest attacks.
3. Claim your social handles
Take the same handle on every platform your customers use, even the ones you will not post on yet. An empty account you control is better than an active one someone else controls. Use a shared company email for these accounts, never a founder's personal address.
4. Make sure the company owns its brand
Your logo, website copy and code are often made by a co-founder, a freelancer or an agency before the company has paperwork. In most countries, copyright in work made by a contractor stays with the contractor unless a written agreement assigns it to the company. The same goes for a domain registered in a founder's personal account. Fix both now: get IP assignment agreements signed, and move every domain and social account into company-owned accounts. Investors check this during due diligence, and it is far easier before anyone leaves.
At launch: protect your email domain
Attackers rarely bother with your trademark. They send email that looks like it came from you. Three DNS records stop most of it:
- SPF lists the servers allowed to send mail for your domain.
- DKIM signs your outgoing mail so receivers can check it was not changed.
- DMARC tells receivers what to do with mail that fails those checks. Start with p=none to collect reports, then move to p=quarantine and finally p=reject once your real mail passes.
Large mailbox providers already require DMARC from bulk senders, so this also keeps your own product emails out of spam. Do the same for every defensive domain you registered in step 2: a domain that never sends mail should publish a null MX record, an SPF record of v=spf1 -all and a DMARC policy of p=reject, so nobody can send mail from it either.

Once you have customers: watch for impersonation
As soon as customers trust your name, someone will copy it. The common attacks against startups are:
- Typosquats: your name with one letter swapped, added or dropped, registered to catch mistyped visits or to send phishing email.
- Lookalike characters: letters from other alphabets that look identical to yours on screen.
- Brand plus keyword: your name followed by "login", "support" or "billing", used for fake login and payment pages.
- Cloned sites: a copy of your homepage or sign-in page on a domain you do not own.
These are not checked by any trademark office. A trademark gives you the right to act, but you still have to find the domain first, and the window matters: phishing domains are often used within days of registration. Monitoring means checking new registrations and certificates for names close to yours, then visiting the suspicious ones to see whether they copy your site or can send email.
When you find one, report it to the registrar or hosting provider with evidence: what the site shows, when you saw it and why it is impersonating you. Clear, factual reports get acted on far more often than angry ones. If you want the domain itself, a UDRP complaint is the standard route for domains registered in bad faith; filing fees start at around $1,500 for one to five domains with a single panelist.
The checklist, with rough costs
- Name clearance search: free if you do it yourself, a few hundred dollars from an attorney.
- Trademark filing in your main market: $350 to €850 per class in official fees, plus optional attorney fees.
- Core and defensive domains: under $100 a year for five to fifteen names.
- Social handles: free.
- IP assignment agreements and company-owned accounts: free with a template, or part of your incorporation legal work.
- SPF, DKIM and DMARC on every domain you own: free, about an hour of DNS work.
- Lookalike domain monitoring: from free for one domain checked weekly, with daily checks on paid plans.
Do steps 1 to 5 before launch, step 6 at launch and step 7 from the day you have customers who could be phished in your name.
