Email Security — Philadelphia & Chester County
Is someone pretending to be your business in email?
Hackers don't need to break into your inbox to impersonate you. They can send emails that look exactly like they came from your company — tricking your clients, vendors, and employees into wiring money or sharing passwords. SkyViewTek stops it.

Warning signs your email is being spoofed
- A client calls saying they got a strange email from you — that you never sent
- You're getting bounce-back messages for emails you didn't write
- Your legitimate emails keep landing in recipients' spam folders
- An employee received a payment request "from the CEO" — from outside the company
- A vendor says they got wire transfer instructions from your email — but it wasn't you
- You've never heard of SPF, DKIM, or DMARC — and neither has your current IT provider
Does this sound familiar?
Email impersonation is happening to Philadelphia businesses right now
You don't have to be a large company to be targeted. Small businesses are preferred targets precisely because attackers assume you don't have the same protections as larger firms — and they're usually right.
"We wired the money — but it wasn't your invoice"
A vendor receives a spoofed email from your domain with updated bank account information. They wire payment to the attacker. You find out when the real invoice goes unpaid.
"Our CEO emailed asking for gift cards"
An employee receives an urgent request that appears to come from ownership — asking them to purchase gift cards immediately and send the codes. The "CEO" is a criminal spoofing your domain.
"A client says they never got our proposal"
Your legitimate business emails are landing in spam because your domain has no email authentication. Google and Microsoft are quietly flagging your messages as untrustworthy.
"A patient got a phishing email from our practice"
A spoofed email appearing to come from your healthcare practice asks patients to confirm personal details. Now you have a HIPAA incident, a reputation crisis, and potentially a data breach notification requirement.
"Someone clicked a link in an email from HR"
A spoofed "HR policy update" email tricks an employee into entering their Microsoft 365 credentials on a fake login page. The attacker now has access to your entire M365 environment.
"Our law firm's email was used in a fraud scheme"
An attorney's email domain is spoofed to send fraudulent settlement instructions to clients. The reputational and legal fallout can be severe — especially without documented security controls in place.
Any of these scenarios hit close to home?
SkyViewTek will audit your email domain for free and tell you exactly how exposed you are — in plain English, no jargon.
The plain-English explanation
What is SPF, DKIM, and DMARC — and why does your business need all three?
You don't need to understand the technical details. What you need to know is this: these three records are the locks on your email domain's door. Without them, anyone can walk in and send email pretending to be you.
01
SPF Record
Sender Policy Framework
SPF tells the internet exactly which mail servers are authorized to send email on behalf of your domain. Any server not on the list gets flagged.
Plain English: It's like a guest list for your email domain. If your name's not on the list, you can't get in — and any email from an unauthorized server gets flagged as suspicious.
02
DKIM Record
DomainKeys Identified Mail
DKIM adds an invisible digital signature to every email your business sends. Receiving servers verify this signature to confirm the email is authentic and hasn't been tampered with in transit.
Plain English: Think of it as a wax seal on a letter. If the seal is intact, the recipient knows the letter came from you and hasn't been opened or altered.
03
DMARC Record
Domain-Based Message Authentication
DMARC ties SPF and DKIM together and tells receiving mail servers what to do when an email fails authentication — reject it, quarantine it, or let it through. It also sends you reports so you know if someone is trying to spoof your domain.
Plain English: DMARC is the bouncer. If an email doesn't pass the guest list (SPF) or the wax seal check (DKIM), DMARC decides whether to throw it out, hold it, or let you know about it.
What's at stake
What happens when your email isn't protected
Email spoofing isn't just an embarrassment — it has real financial, legal, and reputational consequences for your business.
Direct financial loss
Business email compromise (BEC) attacks result in fraudulent wire transfers, fake invoices paid, and stolen funds. The average BEC wire transfer request in 2025 was $24,586.
Damaged reputation
When clients receive spoofed emails that appear to come from your business, their trust in you takes a hit — even though you're the victim. Rebuilding that trust takes far longer than preventing the attack.
Email deliverability failure
Without proper authentication, Google and Microsoft actively route your legitimate emails to spam. Proposals, invoices, and client communications go unread — and you may never know it's happening.
Compliance violations
HIPAA, PCI DSS, and other regulations expect baseline email security controls. A spoofing-related breach without documented controls in place can result in fines and legal liability.
Credential theft
Spoofed phishing emails that look like internal IT communications trick employees into entering passwords. One compromised credential can expose your entire Microsoft 365 environment.
Domain blacklisting
If your domain is used to send spoofed spam at scale, email providers may blacklist your domain entirely — meaning no email from your business reaches anyone until the issue is resolved.
$2.77B
Total losses reported to the FBI from business email compromise attacks in 2024 alone — most targeting small and mid-sized businesses just like yours.
What SkyViewTek does
Complete email security for Philadelphia-area businesses
We don't just configure three DNS records and walk away. We implement layered email security that protects your domain, your inbox, and your team from every angle.
SPF, DKIM & DMARC Configuration
We audit your existing DNS records, identify gaps, and configure SPF, DKIM, and DMARC correctly — including all third-party senders like QuickBooks, Mailchimp, and your CRM. Misconfigured records can break your email; we get it right the first time.
DMARC Monitoring & Reporting
DMARC generates daily reports showing who is sending email from your domain — authorized or not. We monitor these reports for you and alert you to any unauthorized senders attempting to impersonate your business.
Microsoft 365 Email Security Hardening
We configure Microsoft Defender for Office 365, anti-phishing policies, safe links, safe attachments, and anti-spoofing rules within your M365 tenant — layers of protection that work alongside your DNS authentication records.
Email Deliverability Improvement
If your legitimate emails are going to spam, we diagnose why and fix it. Proper SPF, DKIM, and DMARC setup is the single most effective way to improve email deliverability with Google, Microsoft, and other major providers.
Employee Phishing Awareness Training
Technical controls stop many attacks — but your employees are the last line of defense. We provide phishing simulation training that teaches your team to recognize spoofed emails, suspicious links, and social engineering tactics before they click.
Compliance Documentation
For HIPAA, PCI DSS, and other regulated industries, we document your email security controls and configurations so you have evidence of due diligence for audits, cyber insurance applications, and client security questionnaires.

Common questions
Email spoofing & security — your questions answered
Common signs include clients or vendors contacting you about emails you never sent, receiving bounce-back messages for emails you didn't write, your emails being flagged as spam by recipients, or employees receiving payment requests that appear to come from inside your company. A free email security audit from SkyViewTek will confirm whether your domain is being spoofed and how serious the exposure is.
Email spoofing is when a cybercriminal sends an email that appears to come from your business's email address — without actually having access to your account. They don't need your password. They exploit the fact that email was designed in the 1970s without authentication built in. SPF, DKIM, and DMARC are the modern fixes that were invented to close this gap. Without them, your domain is an open door.
SPF is a guest list — it tells the internet which servers are allowed to send email from your domain. DKIM is a wax seal — a digital signature on every email you send that proves it's authentic. DMARC is the bouncer — it ties SPF and DKIM together and decides what happens to emails that fail the check (reject, quarantine, or report). All three work together. Having one or two but not all three leaves you partially exposed.
In many cases, yes — significantly. Missing or misconfigured SPF, DKIM, and DMARC records are one of the most common reasons legitimate business emails land in spam. Google and Microsoft actively penalize domains without proper authentication. After we configure your records correctly, most clients see a notable improvement in email deliverability within days of DNS propagation (up to 48 hours).
SPF, DKIM, and DMARC records can typically be configured within 1–2 business days. DNS propagation — when the changes take effect across the internet — takes up to 48 hours. We handle the entire process and monitor the results carefully. If you use third-party services that send email from your domain (like QuickBooks, Mailchimp, or a scheduling tool), those need to be included in the configuration, which we handle as part of our audit.
Yes. We're headquartered in Malvern, PA, and serve businesses throughout Greater Philadelphia, the Main Line, Chester County, and Delaware County — including Wayne, King of Prussia, Paoli, Berwyn, Exton, and Radnor. Email security configuration is performed remotely, so we also serve clients across the United States.
