How cybersecurity is delivered in Philadelphia
Center City is about two hours from Park Slope down the Turnpike, so Philadelphia is served remote-first and on-site work is planned in advance rather than dispatched same-day. Monitoring runs 24/7 from Brooklyn, and so does emergency service. Our staffed help-desk hours are 4 a.m. to 11 p.m. Eastern time, seven days a week. The proposal states severe-incident escalation, authorized remediation and any other after-hours work. On-site commitments outside our on-site coverage (New York City, Long Island, Westchester, the Hudson Valley, North Jersey and Fairfield County, CT) are arranged in advance and sized to the engagement: a mostly remote engagement needs no dedicated on-site engineer, while an engagement that calls for regular presence, such as vCISO work with someone on site two days a week, can include a dedicated engineer with a drive time generally under an hour once availability, location and the visit schedule are confirmed in the proposal. Hardware can ship pre-configured where the project permits remote setup. Confirm landlord access, circuit diversity, cabling and equipment space before approving a network change. Carrier options to check in Philadelphia include Comcast Business, Verizon Fios and Crown Castle fiber; availability, routing and installation dates must be verified at your address before a failover design is approved.
Who cybersecurity in Philadelphia is built for
Businesses we can support in and around Center City, University City, the Navy Yard, King of Prussia and Conshohocken include medical practices and health-system affiliates on Epic, biotech and life-sciences companies on Benchling, law firms on iManage, accounting firms on Thomson Reuters CS Professional Suite, nonprofits and universities' affiliates on Blackbaud, and contractors on Procore. These are examples of business and application needs, not a list of local clients. We coordinate infrastructure, identity and integration with the application vendor, and identify any compliance requirements during discovery. Companies with an internal IT person can agree a split of responsibilities, systems and coverage hours before work begins.
Continuity planning for your Philadelphia business
Start with the systems your team cannot work without. Record the impact of a building power outage, a failed internet circuit, a compromised account and an unavailable application vendor. Then agree recovery priorities, an independent access path, protected backup copies and a test for each critical workflow. Controls reduce particular risks; they do not guarantee that an incident cannot happen.

A 35-person accounting practice in University City
This planning example shows how we could scope the work. It is not a claim about a customer in this market or a measured result. For published customer work, see our case studies.
A 35-seat accounting practice in University City that handles regulated data in Thomson Reuters CS Professional Suite across the office and remote staff on home Wi-Fi. An enterprise customer's vendor questionnaire has thirty questions and the honest answer to eleven is 'we think so'. Email protection is whatever Microsoft ships by default, DMARC was never set up, the Comcast Business firewall is a consumer router, and the last security training anyone remembers was a poster.
- Barracuda Email Protection placed ahead of the mailboxes and SPF and DKIM alignment checked, with DMARC reporting and staged enforcement to reduce unauthorized use of the domain, with a callback rule adopted for any change in payment instructions
- Cisco Meraki firewall installed with intrusion prevention, geo-blocking, segmentation between finance, servers, printers and guests, and DNS filtering on every device
- A written incident response plan with named owners, the insurer's hotline and counsel's contact, tested on a tabletop exercise
- Monthly review of dormant accounts, forwarding rules, consent grants and administrator assignments, reported in writing
- Microsoft 365 investigation: sign-in logs, forwarding rules and consent grants reviewed to establish whether a mailbox was compromised, then multifactor authentication and Entra ID Conditional Access enforced for every account
- Rapid7 InsightVM deployed for scheduled vulnerability scanning, with the first month's findings prioritized and closed
The exposure is measured monthly and closed, the people are trained against the lures they actually receive, and an incident has a plan with names on it. Leadership sees a written report every month. Terms stay month to month.
Law office: layered security on Microsoft 365 with cloud-to-cloud backup
A 25-attorney firm needed client confidences protected better than a closet server could manage. Alongside a Microsoft 365 migration, NetSys layered anti-phishing and email threat protection, DNS filtering, multifactor authentication on every account and endpoint protection across attorney devices in the office and remote, and established independent cloud-to-cloud backup of the entire tenant because the recycle bin is not a backup strategy for privileged material. The firm reported 82% fewer IT support incidents per month within two quarters.

Compliance in Philadelphia: Pennsylvania’s breach notification law and what sits on top of it
Pennsylvania’s Breach of Personal Information Notification Act, as amended by Act 33 of 2024 includes notice to the Attorney General when the law requires notice to more than 500 affected Pennsylvania individuals. The 2024 amendment also added specific credit-report and credit-monitoring provisions for qualifying breaches. The service scope should identify the records, access controls, retention settings and incident evidence your business needs; your legal or compliance adviser determines which requirements apply. The security service is built to produce the evidence those rules ask for: multifactor authentication and Conditional Access reports, endpoint detection coverage, vulnerability scan results, backup restore records and a tested incident response plan. Discovery identifies missing records and assigns the documentation work. Applicable duties depend on the business, data, exemptions and contracts; your legal or compliance adviser determines which requirements apply.
Primary sources
What cybersecurity costs in Philadelphia
Cybersecurity is priced per user per month when it runs as an ongoing service, and per project for an assessment or a remediation. What moves the number: how many devices and identities are in scope, how much incident remediation and recovery is needed beyond the monitoring and authorized MDR actions in scope, which compliance standard the evidence has to satisfy, and whether the Microsoft 365 tenant is already on Business Premium or the security tooling comes from us. The free external penetration test costs nothing and runs remotely before any of that. Our managed IT pricing page explains how the fee is built.
Who this fits, and who it does not
Best fit: businesses with enough people, money movement or regulated data that a breach would hurt, and no security team of their own: professional practices, healthcare groups, importers, financial firms, nonprofits and agencies holding client credentials. Companies with an internal IT person fit as a co-managed arrangement.
Not a fit: organizations that want a security product installed and left alone. The service is monitored, reviewed and reported monthly, and it changes the way administrators, finance staff and vendors work. If that is not wanted, a tool purchase serves better than an engagement.

Cybersecurity in Philadelphia: FAQs
Can you work alongside our internal IT person?
Yes. In a co-managed arrangement your person keeps the day-to-day and we run monitoring, the security stack, vulnerability management and after-hours response, with the split written into the agreement.
Do we need a security assessment before signing up?
The free external test is where most engagements start. A fuller assessment of the tenant, devices, network and backups is scoped separately and produces a prioritized fix list that becomes the first ninety days of the service.
What does the free external penetration test include?
The free offer is a remote external penetration test, limited to the information available to NetSys and the external scope agreed with you. It examines what your business shows the internet and reports the findings with their scope and limitations stated. Reviews of tenant settings, devices, internal networks or backups need a separate scope.
Do you have an office in Philadelphia?
Our office is in Brooklyn, NY. Center City is about two hours from Park Slope down the Turnpike, so Philadelphia is served remote-first and on-site work is planned in advance rather than dispatched same-day. Outside our on-site coverage the on-site arrangement is agreed before the engagement starts and sized to what it needs: none for a mostly remote account, or a dedicated engineer where regular presence such as vCISO work with someone on site two days a week is part of the scope. A drive time generally under an hour is an option subject to confirming engineer availability and your address. The help desk is staffed seven days a week from 4 a.m. to 11 p.m. Eastern time, with emergency service 24/7. The proposal states the on-site arrangement and any travel in writing, and the agreement runs month to month.
How can IT support help with Pennsylvania data-security requirements?
Pennsylvania’s Breach of Personal Information Notification Act, as amended by Act 33 of 2024 includes notice to the Attorney General when the law requires notice to more than 500 affected Pennsylvania individuals. The 2024 amendment also added specific credit-report and credit-monitoring provisions for qualifying breaches. NetSys can help document the relevant systems, controls and incident evidence within an agreed scope; legal notification decisions remain with your authorized business and legal team.
How much does cyber security cost in Philadelphia?
Ongoing protection is a per-user monthly fee, and an assessment or remediation is priced as its own project. Philadelphia quotes depend on the devices and identities in scope, whether a practice affiliated with a health system needs HIPAA evidence, what a law firm's clients require in their security questionnaires, and planned on-site time. The external penetration test is free.

The free assessment is a remote external penetration test, limited to the information available to NetSys and the external scope we agree with you. Internal reviews and ongoing security management are scoped separately.
